I am installing my D3 today and i disconnected my a/c heater control out of my 05 Tahoe so i could get my hu out easier and now when i cut the air on it blows out hot air like the heaters on. The only thing i did was disconnect two plugs and then plugged them back up. Does anyone know anything about this, do i have to reprogram if it is disconnect. Please help ASAP

sure the knobs are properly attached? plugged everything back in properly?

yes, i m talking to a crutchfield and he has no idea whats wrong

ive heard of this, but dont recall where or the fix... i know real helpful. hopefully all the activity will generate some interest and someone that may have experienced this will see it and respond

there is a reset procidure im not at work until tuesday..if u still have the problem then pm me and i'll send the procidure

so can i install my d3 and then get my air reprogrammed later? or does this void the warranty?

id doubt the thing needs a "reprograming" maybe reset like mentioned, or fuses or something of that nature, Id guess if your install is proper and your confident of no damage you could button it all back up

i guess i meant to say a reset procediure. srry

Could be totally different, but in my mustang (obviously not a GM vehicle as is yours) there are two plugs to reconnect the AC controls. On the plug that connects to the directional controls there is a small gray u-shaped piece on the back of the plug that must be slid entirely upward on the back of the plug; after the plug is connected to the dash piece. I know until that little clip was pushed ALL the way up I had hot AC. The speed controls worked, it was just uber hot. I'm sure your Tahoe is different, but it could be similar. (That little gray thing is also very fragile to all you mustang owners.)

heres a pic. the air wont blow unless the small gray harness is plugged up and the blue harness just controls the lcd screen and so on.

oh god resize!!!

side note, we know have your finger prints and even cell structure dna.

srry these are way to big

do these look similiar jflx60d

The second picture, the more square plug, is practically identical to the plug that controls my fan speed. It is the other plug that has the clip on it in my car. The top pic is very similar to that plug in my car, only in the mustang it installs vertically. I would make sure that dark gray piece on the top side doesn't need to snug in somehow. Also inspect the plug to make sure no small plastic pieces snapped off when you unplugged it

no those are different, but i think your best bet is to button things back up, and wait for
