Hope helps (remember rated this).

Have your motor mounts checked.

You can try lubing the window tracks and regulator but I hunch the motor may be going bad, it has a circuit breaker built into it and it sounds as if it's kicking off and on. I hope this helps. Take care

its vary simple open the hood facing the engine too the far right op to the fire wall witch is all the way to the front on the right hand side you will see a clear plastic bottle with a black top on it you will see the fluid level though the container if you don't see any fluid in it than you will have to have the brake system preged for air in the system. witch is a kinda big deal if you are not mechanically inclined but if there is still fluid in the bottle just buy some dot 3 brake fluid take the cap off and fill it up its that simple hope this helps LARRY B

The heater resistor has probably gone out. It should be located in the blower housing.

It could be anywhere
But let it cool and fill with water see if you can see it leaking. If not fill it to top put cap back on and squeeze upper radiator hose to put pressure in system.
If you don't see anything it could be water pump

I found this for 91.

Incorrect ignition timing or a lean fuel mixture, would be where I would start... Really Depends on engine make??

From Freeport Have to take panel off and rehook the locking arm it's a buger to do

The fuel pump relay gets power from the ECM B fuse, and the relay should be on the firewall or the fender.

I would check the connections & clean them 1st. If it doesn't try to turn over then, a hair dryer works for drying things.

Could be the starter or a wiring problem. You could test for voltage at the starter with a meter or test light. A hair dryer or sunlamp would thaw out the starter if it is frozen.

the problem could possible be a dead short in the wireing, or in the radio its self

You may contact a GM dealer for assitance in getting a manual for that year and model. I would also recommend getting a good repair manual for that vehicle. The savings for one repair will more than offset the price of the repair book. I use manuals produced by Haynes which can be found in most auto supply stores like Advanced Automotive or Auto Zone.

When you flush your radiator, the heater core gets flushed as well. You will have to run the vehicle untill the heater is blowing hot air during the flush, that way its going through the thermostat. Empty the radiator as per normal and thats it.

Any where between 50 & 60 PSI
