zachm89 Posted July 11, 2009 Report Share Posted July 11, 2009 Im sure there has already been a post about this or someone with this problem but my a/c is blowing nothing but HOT air right now. Sometimes it will blow somewhat cool but even with it on max and set to 60* it still isnt cold at all and it doesnt seem to blow as hard as it should. I have no idea whats wrong with it, i have already recharged the cooling system and it reads normal on the gauge. With the temps iin the 100*+ range every day i cant handle this crap much longer. Anyone have a clue as to what it could be? Im pretty sure i can hear when the compressor kicks on so i dont think that its that. I just need to get something figured out quickly.

12'SROCK Posted July 11, 2009 Report Share Posted July 11, 2009 you might need to replace the actuator that controls the door flap to separate the a/c from the heater Quote Link to comment Share on other sites More sharing options...
zachm89 Posted July 11, 2009 Author Report Share Posted July 11, 2009 you might need to replace the actuator that controls the door flap to separate the a/c from the heater ill look into that tomorrow morning...is there any way i can find out if thats what my problem is without just replacing it? by the way killer HID kits youve got, i plan on ordering some next pay day!

See if you can hear the door flaps open and close when you select from the heater and ac. If you verified that the ac compressor is working properly then its more than likely going to be the actuator Quote Link to comment Share on other sites More sharing options...
Fireman31 Posted July 11, 2009 Report Share Posted July 11, 2009 It's called the Blend Door Actuator, and it may very well be your problem. You will need to remove the dash board to change it I believe........ Quote Link to comment Share on other sites More sharing options...
zachm89 Posted July 11, 2009 Author Report Share Posted July 11, 2009 i discovered something new...its only blowing hot from the vents that face the driver, the 2 passenger vents blow whatever it is set on. still doesnt blow 60* or anywhere close but it doesnt blow heat on the passenger side unless the temp is higher Quote Link to comment Share on other sites More sharing options...
wody Posted July 11, 2009 Report Share Posted July 11, 2009 well there ya go, blender door it is! easy to figure out, just a little bit of a project to replace. or you could hire a driver, and you ride shotgun Quote Link to comment Share on other sites More sharing options...

garagemethods Posted July 11, 2009 Report Share Posted July 11, 2009 it may not be gettin as cool as 60* bc you live in tx. i live in tx myself and the a/c really has a hard time keepin up with that heat. Quote Link to comment Share on other sites More sharing options...

zachm89 Posted July 11, 2009 Author Report Share Posted July 11, 2009 yeah, bein in tx sure doesnt make things easy to keep cool but my 03 silvy never had a problem with it, always blew ice cold. ill dig into the dash and fix the blender door and if that doesnt work idk whats next. i just cant take the heat with no a/c anymore, that leather gets HOTTT, haha. Thanks for all the helps guys, i really appreciate it. Quote Link to comment Share on other sites More sharing options...
pnblwzd Posted July 11, 2009 Report Share Posted July 11, 2009 I've had this happen a couple times. You need to have someone with a Tech2 plug in a reset the ac temp control module. This is not a "Reflash" and won't affect any tuning. Quote Link to comment Share on other sites More sharing options...
Red Diablo Posted July 11, 2009 Report Share Posted July 11, 2009 hey bro i know what your problem is, its the Resistor Pack thats loctaed under the blower motor located under the passenger side glove compartment in that black plastic,black plastic comes off with 3 or 4 7mm screws and you will see that theres 2 heavy gauge red black wires going in well that comes off with 2 5.5 mm screws and waa laa thats the problem,try replacing it! i had the same problem before Quote Link to comment Share on other sites More sharing options...
