Hi, I am french, I live in LYON, I have an Trans Am GTA 87 since 1 month, but after the flush of cooling, I has loose the heater and the motor of ventilation works but really less, no ventilation, in position cold or heat, same thing.......just a little bit....why ?

Before ventilation has work good, the heater ...I don't remember.....

If you can help me... Thanks

 

vacume line for heater controls might have came disconnected during the coolant flush

 

Perhaps... I have this version of my car but where is vacuum line for heater controls ?

 

Oh-you have electronic controls-I don't know too much about those,except I think vacume still operates the dampers-electric valves operated by control head switching the vacume ...Nice radio BTW Hopefully someone who knows firebird electronic controls will seethis and chime in...

 

Up, nobody knows firebird electronic controls ?

 

look around underhood for a disconnected vacume line since the trouble started with the coolant flush and also if no heat,might have "air lock"situation in heater core coolant path after the coolant flush-perhaps someone here knows how to bleed a late model thirdgen heater that uses the shutoff valve.

 

thanks for this feedback

Belle Fourche it is french that ahahah

I live in France

 

Hello,

My heater don't give heat... The ventilation is Ok, I removed the cover under the dashboard and when I active the buttom cold/heat, we hear a noise on the motor on the right(on picture) but without the rod or arm moving ? how the rod move ? with this motor and open the door for an access to the heat ?

The motor make some noise but nothing to move, possible to find one ? I don't find on rockauto, someone know this piece ?

 

The vaccum line, if yours still uses one, comes off the back of the engine and goes into the fire wall. Should be a hard plastic line.
