This can be a few different things going on. 1. does the clutch on your compressor engage when a/c is turned on? If so, does it cycle on and off constantely? If its cycling, your low on refridgerant, which indicates that theres a leak. System needs to be checked by professional. If compressor stays on, and you got hot air, it indicates that the problem is with the heater control valve. Normally, this can be found connected to one of the heater hoses located on passengerside engine compartment. It might be electronic, or vacuum operated.

Audi A6 air con always blow very hot air coming from engine with bad smell


The smell is probably related to the catalic converter when a cat goes bad it creates a smell similar to rotten eggs. You might need to replace the catalic converter. This will improve gas mileage and performance. The hot air blowing from the AC is probably a low charge on the Freon.

2006 crown Victoria blows hot air with the air conditioner on the air condition lines are cold under the hood


sounds like the temperature blend door is either jammed or the actuator is shorted ou. when the temperasture control is moved you should hear the door moving...my guess is you are not hearing that..the actuator would be attached to the heater plenum behind dash/glovebox area...becareful to test the correct one as there will be a fresh air actuator and a mode door actuator as well...you can determine which one is which by changing the positions on heater head from hot/col, floor/defrost, recirculate and fresh air settings..each setting will move its designated actuatror..the one not moving would be you temp actuator....have fun!

My air conditioner blows cold air, but my heater doesn't blow warm/hot air... why??


most likely because your heater core is plugged up. this is a repair beyond owner maintenance level.
find a shop which does radiator and A/C work and have them replace it
