i have a 05 AT coupe with 43xxxmiles on it. i just turned on da AC today and it started blowing hot air. so maybe i thought it was cuz i haven't been using it all winter so i sat there and waited for a while and it was kept on blowing hot air! and when i turn da AC on i can hear da AC compressor kicking it. so what could it b?!?!? i'm thinking i need to go charge da freon. but it worked fine last year. i searched and searched in da tech section and i couldn't find anything about AC blowing hot air. i need 2 fix this b4 summer comes cuz where i live it gets over 100 degrees in summer! thanx guys!

 

check the plug to the ac condenser and liquid tank in the front behind the grill

 

I agree. First check your radiator fluid level. Next, you may want to think about getting your A/C system checked for leaks. Sure you could get it recharged but if there is a leak, you will be back to square one sooner than later. Good luck!

 

i couldn't find that...

ya my radiator fluid level is low but not below da line. so i don't think thats not it. today i tried 2 turn da AC on again and for like da first couple seconds cool air blew and then it turned into hot. i just changed stock intake box 2 popcharger couple times past month cuz i had 2 take my car in for powertrain warranty work done. maybe i disconnected something there?!? is there anything major by da intake?!?

 

you could have an air bubble in your system. Do you hear any bubbling or boom sound when you turn on you AC/heater?

 

i have the sameeeeeeeeeee problem. i had my freon filled and still just hot air. idk what it could be

 

my 2003.5 started having this problem at the first on after winter. Infiniti dealer told me I need the compressor and belt for $1400. Did I hear right? $1150 just for compressor.

 

WTF?!? R U SERIOUS?!? I FVCKIN HOPE ITS NOT that in my car. cuz i can't afford plus summers right around da corner. and it gets 100+ degrees out here during summer!

 

oh god no :[

nice link massios

 

^^^ ya... i read that thread a few months ago. that screw dug a lil tiny hole on my AC line but i don't think it did enough damage.

 

I realized I have a tiny hole in my line. Can it be fixed or does the entire line needs to be replaced?
