Where is the turn signal flasher on a 1997 GMC Sonoma?

The question is for a 1997 sonoma however the answer refers to a 1994 sonoma, and after trying this on my 1997 sonoma with no luck I found the answer under "Where is the flasher unit on a 1997 Chevy S10?" which is exactly where I found the flasher units for my 1997 sonoma and it was indeed the right flasher unit which was for the signal.

AnswerI have a 94 Sonoma and to locate the turn signal flasher, inside, under dash, on left side is a plastic sound protector, mine had 3 screws holding it up, drop this down and straight in you will see a 1" round thing - this is the flasher, pull it out and replace with new one (there are two flat prongs that plug in). It appears this is a well guarded secret!

How do you remove the dash cover on a 1995 GMC Sonoma to remove the heater control switch?

Hi, I just finished doing the same thing. There is a plastic ring around the radio and heater that pops off, just pull it off gently. It doesnt have to come all the way off to get to the heater switch. There are four hex screws holding it on that are visible once the ring is pulled out.

Where is the oil filter on a 94 GMC Sonoma?

2.2L cavalier motor... I have no idea. It's really obvious when you're under the truck though. So obvious that I can't be bothered to remember.

2WD V6 look near the LH side of the block.

4WD look under air filter or behind access panel under front of truck.

Where is the pcv valve located on a 1996 GMC Sonoma?

Hi, I have a 1996 GMC Sonoma with a 5 speed manual trans, 2.2 liter (4 cylinder) engine. The pcv on my Sonoma is located on top of the valve cover on the FRONT portion of the engine. It is held in place by a screw in star shaped plug. To get to it remove the square plastic cover with GM on it that covers the accelerator cables (1 small screw on top of cover), pull the hose off, pliers to loosen plug, unscrew plug and pull out PCV.

THE HOSE going to the back of my valve cover is just a vent tube, the aluminum tube sticking out is NOT the PCV, just a sraight through tube. Lee

Why would you be getting code P0300 on a 2001 GMC Sonoma if you already replaced the coil for cylinders 1 and 4?

How is the ignition module? PO300 is a multiple misfire code. It can have many different causes. Coil being one of them. The 4.3 motor that you probably have is susceptible to the (sometinmes called: octapus or spider) fuel injection unit that set on top on the engine. I believe there was also a poppit valve problem on them. Do rule out basics like spark plug or ignition wire or poor connection at the coil from corrosion. you have to reset the computer and see if it still comes on then check the injectors

Radio

In a 2003 sonoma how do you find code for radio?

You must go to your GMC Dealer. They can get a special code out of your radio then call an 800 number and it'll give them the unlock code. they will then enter that code they receive from the 800 into your radio and it will be unlocked. you might have to prove ownership of vehicle for then to do this - the reason for this is to prevent theft of radios

How do you replace door hinge pin bushings on a 1992 GMC sonoma?

First off you need to take off your door panel using the proper tools so as not to destroy any push clips. You than have to disconnect any wiring if your truck has power windows or locks or such. Once this is done you get yourself a hammer a pin punch and a friend to hold the door. Hold punch on bottom door pin and hammer it out, than repeat this step on the top pin. You will than be able to remove the door. Your bushings will be on the hinges themselves. Use your pin punch and hammer to hammer the old bushings out, then hammer the new bushings in. Get your friend to hold the door on again with you and install the hinge pins starting with the top one. Once the door is back on reconnect your wiring in the door should you have any and snap on your door panel again. Book time at a body shop is a little over an hour to do both doors.

Fuel Filters

How do you replace the fuel filter located on a 1995 GMC Sonoma?

I take the old filter out with the ring still attached and after measuring the location of it on the old filter I carefully tap that ring off. Measure the location on the fne filter and slide the ring back on tapping it carefully to the same location as on the old filter. Then reinstall the filter sliding the lines into each end and then attach the ring to the frame with the bolt, tighten the fitting on each line, start the vehicle and check for leaks.

The fuel filter is attached to the frame of the truck right below the door post of the driver side door. It is an in-line filter and is held on by a plastic strap that holds the filter as well as the return fuel line to the gas tank and (I believe) the brake lines that go to the rear wheels. I was not able to slide the old fuel filter out of the plastic clamp when I tried to change the filter, but there may be a trick that I don't know about. Anyone else know how to slide the filter out of the plastic clamp?

  • On a 1995 GMC Sonoma the fuel filter is located below the drivers seat and is attached to the mainframe via a plastic clamp. The fuel lines may have pressure, use caution when disconnecting. The fuel lines provide some flexibility and will allow the filter to go in and of the the plactic clamp. In addition, the fuel lines will determine the alignment of the filter above and beyond the ability of the plastic clamp.

How do you know the proper rear brake adjustment on a 1987 Oldsmobile Cutlass Supreme?

Assuming it is rear DRUM brakes, adjust the shoe until there is friction when spinning the wheel or drum, back off a shade.

Most have self ajusters on them. Ajust them out until the drum will hardly fit back on. After you put the wheels back on and your done with putting the brake shoes on. Find a place where you can run your car in reverse safely. Go bakwards about 25 miles an hour and hit the brakes hard. Do this several times and they should ajust themselves out to where they should be. This is assuming like above we are talking about the back brakes and they are drum style brakes.

How do you replace the fuel pump in a 99 GMC Sonoma?

If the year is around a '92 the pump is located in the tank under the sending unit for the fuel gauge. They are not the most exciting thing to replace as i have just done one in a 92 S-10 by droping the tank

If you have a V-6 it is easier to remove the bed and access the top of the tank that way. On most V6 Sonoma and S-10's the exhaust is in the way of removing the fuel tank, you can lower the exhaust but then it will rest on the differential and you will have to lower that also. I have a good friend that is a 35 year GM Mechanic, he says ignore the books and remove the bed. There are usually just 6 bolts that hold it on, have some beer ready for your friend that will help you sit the bed out of the way.

Mine is a 98 4 cylinder, you can't buy just the pump. The whole assembly is $330.00. Look it up on autozone. Crazy.....
