when you turn on the ac the idle air control should go higher and raise the idle up. the tps should stay the same. the IAC should open up and let more air through to make the idle go up higher for the additional load the ac puts on the system. While this does affect your idle rpm it shouldn't change the tps

In Forum: Chevy Cars

continues to run normally or does it cough and run badly? how long does it run? How do you turn it off if it keeps running? Does it turn off if you open the door? has anything been done with the radiator fan circuit? (Any wires spliced in to make the fan run?)

In Forum: Ford Trucks

without any description of the noise or when it happens I would think to look at the work that was done and see if something is not correctly re-installed

In Forum: GMC Trucks

you should take off the air temp door motor and see if you can change the temperature by moving the door manually.the motor could be bad, the door could be stuck or the door could be broken.

In Forum: Chevy Trucks

I would check for some sort of blockage of if the drivers side defrost connection has been moved and doesn't line up correctly. Anything been done under the dash recently?

In Forum: Ford Trucks

I'd check for the correct fuel pressure first.

In Forum: GMC Trucks

not sure what your problem is. Is it that you don't get the hot or cold temperatures or is it you don't get the different modes, floor vent and defrost? ac/heat (temperature) are from the blend door and the floor, vent and defrost are from the mode door.


Thank you for the help, was great, for what I would of paid at the Dealer ($110.00) your mechanic helped me for free and it was done in less than 30 min. Awesome web-site, thanks again.

Awesome advice. It's nice to know that even a tech that is having trouble diagnosing a problem has some place he can go to bounce ideas and seek advice from other certified Tech's.

It is so nice to have a website all about car that even a woman that does not know anything about auto repair can come to and get some free help.
