The lights that light up your gauges. . . I don't think those are the lights being asked about. More likely you are inquiring about the service and warning lights.

Check Engine Light

How do you reset the check engine light on a 1994 Mercedes Benz E320?

under the hood (I think on the driver side near the firewall) there is a small box. When the top is removed, you'll see a bunch of numbered holes (look like a diagnostic connector), an LED and a button. This is the computer diagnostic center.

By pressing the button, the codes can be shown with LED blinks.

here is the process for checking codes: http://mbca.cartama.net/archive/index.php/t-12110.html

this link has the codes (also a great W124/W140 site): http://pages.prodigy.net/jforgione/MB_DM.html (caution, his example is a W140 so the diagnostic connector is different, but the codes are the same)

When you have retrieved all the codes, hold the button down for 6-8 seconds. When you turn the key off, and then start the engine, the CE light will go off. (sometimes this needs to be done twice or three times) Your welcome, i love you too. lol

Turn Signals and Hazard Lights

Where is the flasher to fix a left turn signal that is stuck on?

Hey Tina==It is a burned out bulb that is the problem. Find out if it is front or rear and take the light assy off and change the bulb from the rear. If you told me what kind of car you have and model, I may could have been more specific. GoodluckJoe If you have a W126 and your left marker lights stay on, try twisting your headlight switch clockwise one click, to the "off" position.

Does a 1987 Mercedes-Benz 300D turbo diesel sedan have rubber seals in its' fuel system?

There are rubber hoses that will eventually leak when using biodiesel which, I assume, is why you ask. The injectors and injection pumps don't seem to have any such difficulties.

How do you remove a Turn Signal Switch on a 1996 Mercedes Benz E320?

im not 100% sure on the deatils... but heres an idea.

Before you start... make sure you straighten the wheels and try not to move it the whole time ur doing this or u can be in big trouble.

There should be 2 screws/Alan key (cant remember exactly) behind your centre of the sttering wheel, once you unscrew this your airbag should come loose.

Unplug the airbag and there will be a coil inside... DO NOT ROTATE... there wil be a big Alan key in the center, once you unscrew this the turn signal switch should be loose...

its pretty simple, but just avoid rotating the coil and remember as best as you can how it was when u opened it... i was told this can mess up a lot of things if this breaks.

hope this helps

How do you fix the sunroof on a 97 Saturn SC when it goes up and down but will not open?

I currently have a similar problem. It seems that one arm on the sunroof is frozen in place, while the other arm can move. I kept playing with the button, hearing a bit of a grinding sound - probably the gear teeth on the left arm (the one that is frozen). While messing with the button the right arm proceeded to move back a little bit at a time, but the left one did not. When trying to close the sunroof again, the frozen one would not move back (of course), but the right one did not move back either, so now it is cockeyed and stays paritally open all of the time.

I spoke with a sunroof repair person, who told me it would take a couple of hours just to bring the arm back down so that I could at least close the sunroof all the way so it wouldn't leak. That would cost $130. It seems like at least the motor would have to be replaced and possibly one or more arms of the sunroof.

http://www.sunroofdoctor.com/ (http://www.sunroofdoctor.com/guideinspection.htm).

Not sure if I helped or not, but it looks like it would be a few hundred bucks to get it fixed. I think I will just get the arms back in place, put the glass back in, and take the fuse out, so that no one tries to open it again.

Jim

I have a 92 SC & had to replace the sunroof relay. It controls the up/down & open/close functions. It's located above the headliner at the front of the sunroof & it's easiest to remove the headliner to access it. Also, it's a dealer part....part stores can't or won't get them. .

The 85 300 SD keeps running after the key is turned off How difficult is it to replace the fuel system cut off solenoid?

AnswerYour vacum system could be of failure or a single vacum line or vacum lines could be leaking thus leaving no vacum to shut the engine down. AnswerThe car will not shut off because it runs on a vacuum system. There is a manual "shut Off" red button on top of engine for manual shut off. Problem usually is: 1) Door lock seals have cracked and letting air into the lines or 2) vacuum pump is no good. For 1) need to replace door lock (is a pain to do). Simple fix is open hood. Above steering column is a bunch of vacuum hoses. You'll see the main one coming from the vacuum pump and then branches to many other lines. These hoses are designed so you can pull them apart. First check, follow main line from vacuum pump and pull apart hose and put finger on to see if you are getting good vacuum. Second, Yellow? line going into firewall (under dashboard) goes to the doors. Pull this line off and put finger on to feel vacuum pump sucking. Engine might now cut out if the problem is the door seals. Temporarily I have put a piece of plastic over the hose with rubberband. Obivously you loose automatic door openers but great temporary fix. If it is vacuum pump, don't bother with vacuum pump seal, just get the whole new part. It is relative easy BUT need good alen socket. Also, crank engine so when you install the pump spring isn't letting the pump go down. (just crank the engine w/o starting before you put pump on so pump sits flush, you'll see what i mean. Go to www.alloemautoparts.com for best prices. New AnswerThe fuel cut off solenoid is a simple bolt on, however long slender hands and fingers are a great asset. If installed incorrectly the engine can 'run away' meaning rev uncontrollably until destruction. The stop lever will not work in this situation. I suggest you have another person start the car while you prepare to block the turbo inlet with a damp rag over a small piece of 2x4. Should the engine attempt to 'run away' you can block airflow and suffocate it to stop.

The most likely reason is a door lock vacuum is leaking, lock each door one at a time and see if one door eventually builds up enough vacuum to shut off the engine, then you know which door vacuum unit to chasnge inside the door panel. The rubber boot becomes brittle and leaks. Or there is a vacuum hose pulled off or cracked inside the engine compartment. Last resort is the vacuum shutoff behind the injector pump.

How do you replace the heater blower on a Mercedes Benz?

the only thing I can tell you is go to manuals unlimited .com and get the CD manual for your car and then go to download.com and get adobi reader and that will give you the best info on it. I have 2 one for my 450 sl (73) and one for my 300e. it was only $20.00 each and is the same man that you will find from Benz .

Ok I my fan would come on sometime somtime not, 1985 Mercedes 380 seI finally got tired of this it finally got tired of me hitting the panel in front of the passeger seat and it would come on.This is what you want to know.on the passenger side under the dash there is a black cover large with one screw in it, remove it, then there are two black snap levers you need to pry gently and the rear of the panel will come down. the rear is towards the trunk.thene there is light dark gret cover. with two screws remove them. then your blower is exposed. remove the three screw holding the blower on, remove the electrical connections, slide the connector from the housing. You then will have the motor and blower in your hands. My motor armature brushes where worn terribly, and ethced the armature. you can get complete motor or assembly about 125, motor only 99.00, I haven removed the fan yet so i don't know how to carefully pry it of without breaking. If you want more Mihali@cox.net. Let me know what you found out. Mitchell.

How do you release a hood latch on the drivers side of a 1999 Jeep Cherokee Sport?

AnswerI had the same problem on the passenger side of my 2000 Sport. Went to have my oil changed and they recommended a body shop because they couldn't get the thing open either. Before doing that we decided to try spraying the latch with WD-40, a bit tricky since we couldn't get the hood up on that side, but after several generous attempts the latch released and I haven't had a problem since.

I also had the same problem only once on my 2000 Sport...Had to take to body shop who charged me $40 to free it. They told me they just kept pushing no the center of the hood and trying to spray in WD 40 anywhere they could....Best thing to do...keep all hood latches lubed! once a month at least....
