I HAVE A 1984 CRX. HEATER DOES'NT BLOW AIR OR AIR CONDITIONER. NO ANTIFREEZE SMELL. DOES THIS MEAN I ONLY HAVE A BAD FAN?


You are correct! If there is no air coming out no matter what setting you have it on, this is caused by the blower motor being burnt out.

Have a good one!

The air conditioner is not blowing any air at all on any setting. A/c, heat, defrost etc..


check fuse and relays, if its good, have blower motor check, if the motor is good, check the fan speed switch itself

Air conditioner in 2005 jeep wrangler x


Yeah, I would go up hill or pull away from a stop and the A/C would cut out and then come back once my speed was stabilized. It was a vacuum hose leak !! This mostly affected the upper dash blower fan.
