the other day i pushed the recirculate button on my heater controlls and the light flashed at my about 5 times and that was it. is the light supposed to stay lit when its on recirculate, or is it supposed to just flash then go out??? scanned it with the snap on scan tool at work and had no codes.

my factory service manuals arent telling me the answer, however for diagnostics it talks about having the mode switch in "vent" for testing, does recirc only work when you have it on vent???

 

i think on defog/defrost it doesnt work

 

well, i know it dosent work on either mode with defrosters, and i know it does work with regular vents

 

Was it blowing on you or the windshield? Mine will always blink and never blow recirculated air at the windshield. (Maybe it´s broken on my car, but thats how it has been since day one)

 

x2...

 

there are certain modes that won't allow the recirculate function... can't remember which ones but I am pretty sure it's when you have defrost going

lol you guys are fast :P

 

my 04 redline recircs on all settings

 

i never really played with it much, just tried it and it didnt seem to work and kinda left it at that. ive only got 1000km left on warrenty so i guess if its an issue i should get it to the stealership.

 

It only works on the vents and foot well. Not on the defrost selection.

 

yea i determined that on my way to work today. not that i actualy use recirc, but if it didnt work i could cost gm more money to fix it lol.

 

Doesn't work on feet and defrost

/thread

 

it works on feet if you have the body vents on. but as soon as you select full feet and clockwise it wont

 

Thay is why I said feet and defrost...not feet, bi-level and defrost

 

oooooo gotcha i see it now

 

fyi:

Recirculation Operation
The recirculation actuator is a 2-wire bi-directional electric motor. Two control circuits enable the actuator to operate. The control circuits use either ground or a 12-volt value to coordinate the actuator movement. The HVAC control assembly reverses the polarity of the control circuits to move the actuator in the opposite direction. The recirculation operation can function with blower motor in either the ON or OFF position. The A/C compressor automatically comes ON when recirculation is selected.
Recirculation is not available in Defrost and Mix-Blend mode.
