I bet its the Heat / AC control unit....the slider that goes from hot to cold is probably broken, I replaced mine 2 times already in my 94 and need another

The slider has a wire that pulls a lever to open from hot to cold, its plastic and breaks inside, its on the top right back corner of get to it you must remove the arm rest top pad only , then the covering for the shift, there are 2 screws in the arm rest to remove shift cover, then you have to remove the facecover for the heat control unit ...

When you remove the shift covering there is a little plastic cover inside with a noch that marks where the shift goes to Park, Drive, Neutral you will see or hear it move just replace it so you know what gear your in when its put back together

1984 c4 corvette rack and pinion

In a nutshell, you disconnect everything attached to it and slide it out the passenger side between the subframe and frame. Obviously, you have to disconnect all of the fluid lines, the tie rod ends on both sides, and the 2 (or 3) bolts that holds it in the car, along with the steering shaft.

My C4 Corvette wont allow the heater or the A/C to come on. I replaced the control panel and everything on it works. Temp, blower etc: All fuses check out as OK. What's next in line to check?


C4 Corvettes have an Outside Air Temperature sensor which may be faulty. It senses air temp in front of the car and tells the climate control unit (which controls the heat/ac) what the temp outside is. Yours is in front of the grill. It's a $20 part. It looks like the attached link. I'm not sure if this is your issue, but it was on my son's car. I just thought it might give you a direction to check.

1985 corvette headlight close but wont open

I did mine about 3 year ago, C4 headlights are electric motor driven. Clean the contacts, if they are clean, you will have to replace the gears, it's really not hard, just be sure to clean everything as you re- assemble the motor drive. I used synthetic grease. The drive can be unscrewed from the housing and then changing the gears is easy. Most gear sets have directions with them. I got mine from Corvette Central. (about 50 for the set, replace both gears) Be sure to remove any debris.

Heater and ac controlls not working 1994 corvette

Are all the vents working? Does your Cruise Control work (properly) it may work and shut off. If your vents are working is only hot air or cold air coming thru, or just your defroster vent?

You have a 3 way check valve under fuel rail guard on passengers side, its a pastic barrel shape thing it rots and creates holes in it causing your ac vents and cruise control to malfunction.

next your heater control unit if you have the one with a slider to regulate the hot or cold temperature breaks easily inside unit, its only plastic. Its an arm inside unit to control the temp in car it slides a door open or closed for heat. If you look where he slider enters thru that hole space you will see a post it sits on to open and close .

I am working on the drivers door window of a 1994 Corvette C4 coupe. Having dufficulty lining window in the closed position. Front of glass rides up in the up position. There is no adjustment to counter...

If the window is skewing front to back or vice versa on the way up, the window is dragging on one of the guides - window is too tight or loose in the guides or a window channel in the door is not aligned properly. Resistance at both the front and back of the window in the channels as the window moves up has to be pretty much exactly the same.
