SOURCE: Starter in a 1992 GMC Sonoma 4.3 v6

bottom rear of engine on the passenger side, the starter is serviced from under the car. it is held to the engine block with two bolts, then u must remove the battery cable and starter solenoid wiring as well, always disconnect the battery before doing any work on the starter.

SOURCE: Replacing heater core in 2000 GMC sonoma. Dash is

If the dash is removed you've saved about 9 10ths of the job endurance. Look around, what you believe to be, the perimeter of the heater box. I cannot, and no one else can, tell you exactly where the bolts and nuts that mount the heater box are. Therefore you must viually sixe the box and check outide in the engine compartment and inside under the dash for the mounting bolts.You'll want to start by removing the heater hoses. Then starting at the passenger side engine compartment look for a group of 10mm or 7/16ths nuts retaining the housing and remove them. Do the same inside. The housing is usually held together with screws or clips, it changes year to year. Keep a log or pix of the wires and cables and hoses(vacuum) that are connected to the housing for reassembly. You'll need to "roll" the box out from under the dash depending on how much of the dash has been removed. The core is easy to spot for is has two hoses sticking out, and, is encircled with clips or screws . Also make sure you remove the bracket around the two entry hoses if it has one. Thank you, Dana

SOURCE: Heater does not work

first make sure you have anti-freeze in it and there is no air bubbles in the system and if you are talking about the blower motor make sure all of wires are good and the temp limited switch next to the blower motor is good give these websites a try www.alldatadiy.com and www.autozone.com if all fails stop by your local library and get your hands on a Haynes auto repair manual for your truck wish you the best of luck Michigan Man.

I have a 98 GMC Sonoma and the A/C will not work. It only blows heat even when its in the Max A/C position. Do you think this could be the blend door actuator? It is manual not automatic


Yes - a blend door is definitely a possibility, especially if it blows heat. If the A/C was low on freon - the temperature would be at least ambient temperature.

My 1996 GMC Yukon does not have any heat, just blows cold air what could it be


Check coolant level. if ok then see if engine comes up to temp. 190+ at thrmostat housing. If not, replace thermostat. If thermostat is ok, feeel heater hoses. If one is hot , and the other cold, then remove both and flush heater core. If both are hot, suspect blend door problem in heater box. probably need pro help for that.

My 2001 gmc sonama heater doesn't work ..only blows out cold air...what's wrong?


This no heat problem is one off two things, you may be low on coolant and its not flowing into heatercore or the actuator motor that controls the blend door is bad, the blend door is a door in the heater boxs that opens or closes to give you hot air or cold.

I have a 2000 GMC Sonoma. The heat gets warm until the fan is turned on then the air turns cold. Acts like it is not switching over from ac to heat. what can i do about it?


Probably the blend door not actuating. I do not have the manual on where your door actuator is. It's usually right of center under the dash. Look under there and see if you can see anything trying to move when you change the temperature setting. Also, if you hear a clicking noise, that would be the actuator stripping it's gears. If youy can find the actuator, take it off and see if you can manually rotate the door hinge. If yes, replace the actuator. If not, you will have to remove the heater box to find out why the door is jammed. The actuator looks like this:

Heater does not work


Check blend door motor for proper operation (vacuum operated) if necessary, detach arm from heater box and move by hand. If you have heat then, change motor! You are reaching operating temp for engine, right? If not, thermostat is stuck open... Change.
