Air conitioning problem

[nick eversole]

Ok I have an 01 gtp, air conditioning is cold and strong... When it turns on. I start the car and turn te knob and nothing happens no heat or air just won't turn on. I leave the knob on and hit rail road tracks or a big bump it turns on and works fine. And if u turn off the car an turn it back on I he to hit a bump for it to work again, any ideas?

do you have a water leak on the passenger floor board?

[nick eversole]

Acually I do most times it rains I fight the damn water cld that have shorted it out or wld it completely ruin the motor?

[brandonl2000]

lol yes that is probably your problem. im glad he asked that question. it drains right on top of the motor and if you dont fix the leak in time it will short out the motor.

[nick eversole]

Well hell, guess I'll start looking into buying a new motor winter will suck trying to find track to hit every time I want heat lol, ok thanks again guys

before you buy a motor, buy this and fix it. http://www.grandprixforums.net/water...-fix-6961.html

I asked that because what mine is doing is leaking through the motor and making the bottom of the rotor rust and lock up. I turned on mine, and hit the motor a few times with a wrench and it started working again. I would recommend fixing that water leak before replacing the motor or it will just happen again
