i just installed my m7 cold air intake and now my a/c does not work!

 

ps

i dont have auto climate and the a/c light is not coming on

 

that makes no sense. you dont touch anything near the ac for the intake. try unplugging your ecu check all the connections and plug it back in

 

I reset the ecu as suggested and still no A/C. I think I know what I did wrong I just don’t know how to fix it. I got so excited about the M7 CAI that I did not disconnect the battery until I got to the fuse box and it sparked. Now, I have check all the fuses that appear to be A/C related and they are all good. I also noticed after a drive that my radiator fan is not kicking in. The same with the compressor. So it has to be a fuse that I blew I just cannot seem to find it.
Any help would be greatly appreciated.

 

check all fuses with test light and they are all good. what else could it be?

 

They are in noway related unless you really screwed up the install....
Just a odd chance that the ac stopped working unless you remember bumping up against the hoses/condenser.....

 

id bet because your fan is not working right that your ac wont kick in?
test the voltage at the fan when you kick it on, also test for voltage at the ac compressor when you kick it on.
and have it checked to make sure it still has charge in it.

 

so after checking all the fuses, voltage on the fan and compressor i finally found the problem. the freakin climate control button was stuck. i jabbed it a few times out of frustration and its working now. what are the chances this happens when i go to install the cai! ugh! thank you all for your help.

ps
the m7 cai is great. not too loud just enough sound so you know its there. ofcourse it gets louder in the upper revs which is a good thing. as far as performance goes. it smooth out the idle and it seems to rev quicker. but, that could also probably be attributed to the dirty cheap fram filter i replaced.
