The EGR valve is located in the center of the intake, at the front of the engine, between the alternator and the A/C compressor. I've added a picture of the location to the links on the right. It is titled "Picture of EGR valve location, on 1996 - 2001 4.3L (262c.i.) Vortec V6 engines"

Piece of cake. Pop out little rubber plug where arm meets tailgate and unscrew the nut, pull off inside panel on tailgate, remove a few 10-13mm bolts around wiper motor, remove retaining clip, unscrew plastic retaining nut on outside, and swap out with new one. Best bet is to go to a junkyard - $40-$50 or $90-$150 brand new!!!

It might be your clockspring. (actually most likely it is your clockspring) try turning the turn signals on and turning the wheel from left to right all the way and then back again. you should hear a click noise in the steering wheel and the turn sigals should stop blinking if not your tab or something is not right on the clockspring. this requires removing the steering wheel and some special tools as there is a spring in your steering column. good luck The multifunction switch is bad. This is the switch that controls the trun signals, wipers, and cruise control. It is a multifunction switch Problem. This is the switch that controls the trun signals, wipers, and cruise control. The assembly is easy to change if you have any skills.... Took me only 50mins and my dealer wanted to charge an 1hr and 1/2

there is no power door lock relay,there is only a circuit breaker located in the fuse box under the dash. gmjim There has to be a relay somewhere in the wiring. I have an 89 s-10 and they sell a replacement part for it. Its gotta be there cuz I'm looking for mine as well. I suggest looking up the replacement part(any parts store online should have a picture, I found mine at autozone) and getting the picture so you know what you are looking for. I have a feeling mine is inside the door.

The starter on a 1997 gm jimmy is going to be under the vehicle on the passenger side of the transmission and you take off the wheel and that back guard that's held on by Christmas trees that's what i call them and on the top of it there should be a shield and you have to take that shield off if there is one and then you will have a positive and negative on it and before you touch them you need to undo either the positive or negative battery terminals and then take them off and after you do that and take off the positive and negative off the starter there will be two bolts holding the starter in place and loosen the bolts off of the bell housing and pry it down and away from the starter with out messing it up then put a shim in it to hold it and the bell housing and starter should have a notch in them both to where you can pull the starter out but its going to be very aggravating but just jiggle and move it around and it will come out and put it back in how you took it out and the new starter most likely will not come with a shield so take your old one and put it on when you have the new starter up in there with both the negative and positive cables back on but that's pretty much how you change a starter in a 1997 GM jimmy

On the newer models you just need to remove the belt, disconnect the connector on the backside of the alternator, remove the two bolts and then reverse the process. You will need a ratchet to relieve the tension on the belt via the tension pulley. Always disconnect the battery first!

gas gauge sticks either full or empty

This is a known problem with Chevy's that they will not recall on. I had same problem with my 2000 Blazer. Had to replace fuel pump / gauge assembly in tank. It took a couple of hours to do, but was worth the headache having a gauge that works now, No more running out of gas or watching mileage.

I replaced the water pump on our 98 jimmy last motnth you will need to star with removing the raditor and the fan clutch fan. Once these items are removed you will have a clear picture on the water pump and the bolts that need to be removed.I am not a gear head and this took me two hours from start to finish.

Blown fuse, blower motor, or switch. IF the Heater Control Valve isn't getting Vacume or 12 Volts(IF Electric-IF the Heater Core is Blocked or Heater hoses Kinked-OR EVEN a bad ACTUATOR DOOR-I Don't know if u are talking a Blower Problem or WATER Circulation Problem. MY Jimmy stopped producing "heat" through the vents. The fan worked at all speeds, but all it blew was cold air. I actually did not notice until winter hit. If this describes your problem try flushing your cooling system and replacing your thermostat. I tried just flushing b/c the thermostat looked upon visual inspection. I get hot air now after I put a new one in. After losing hot air in December '04, I discovered that my 1998 Jimmy had coolant grit blocking the heater core on the inlet. Removing the hoses from the core and backflushing did the trick. The guys at the local Jiffy Lube flushed the entire system and converted me to green coolant. I've been OK since (4/2005). After having this problem: Even during 2 hour drives the engine temp needle wouldn't move and therefore no heat in the cabin for 2 years in my 1998 GMC Jimmy w/ 4.3L V6 Vortec 4WD, and getting not so good mileage (about 9.5-11 mpg) I turned to the old owner's manual (something I or any other mechanic would rarely do!). There in the scriptures lie the answer 87 OCTANE!(Mid-Grade) My Jimmy now heats up to normal operating temperature within minutes despite the cold days of Colorado winter and costs me a lot less at about 14-16.5 mpg average fuel economy. I've noticed that most Jimmys don't have the digital fuel economy readout but mine has shown me what a difference 10 cents at the fuel station can do and also has the side effect of comfort in the form of heat. So if your SUV requires a higher octane fuel (read the owners manual), then it really, I mean really, requires it. (4/2006)

had an 88 that somebody put in a tail light bulb wrong, and was back feeding & would stall the engine every time

Yes, when I saw this issue, I immediately thought bad grounding. Check that the ground strap between the engine and the frame of the car is secure and has good contact. Had a Fiat one time that did the speedo thing when this condition was present. Did lots of wierd things until the strap went back on

Could be your TPS (throttle posistion sensor) sensor

I just need to say that it's very unlikey that the taillight builb in the 88 was the actual problem, an 88 didn't have enough elecftrical systems to have problems with electrical feedback.....and it most likely is the TPS (throttle position sensor) or the IAC (idle air controller), the ground wire that is connected on the bottom left (from standing in front of the truck) is actually an extra ground but there are some systems that use that as the main ground. Check that ground anyway because it is a common problem for those gm's (Chevy and gmc, both gm vehicles) but test your IAC and TPS first

If this is a 4X4, this can be a little tricky, you can access the wiring to starter through the wheel well, this starter is probably expensive, as it is smaller than the average bear. Good luck. HTH

You first need to look under your passenger wheel well and remove the nut that connects your wire to the starter (also there is another wire with a smaller nut to disconnect from the starter). Next remove the cover plate that�s directly below the front of the starter, there should be six bolts to remove. Then remove the two bolts out of the starter, after the starter is loose. You then should be able to angle the back of the starter up towards the wheel-well. Now you should have enough room to take the smaller wire off of the back of the starter. After that�s off you�re able to remove the whole starter from your car.

You need bushings in the bottom door hinge. You might have to remove the finder to get to it. You might trying to go to a you pull it and find a good hinge from a 89 to 97 Thunderbird or Cougar. It would be less work.

You have to remove the wheel hub and remove the c clip in the hub that secures the bearing. You can have the bearing/races pressed out or you can use a slide hammer to remove them. You will need to take care when installing new races that you don't scratch or nick them by using old races over the top of the new ones to drive them in with a hammer. You may just want to remove the hub and take to a shop and have them do it for you if you don't have the tools.

To replace the fuel pump, you must unhook the fuel lines from the fuel tank and remove the fuel tank from the vehicle. The fuel pump is actually inside the tank.
