Engine Size: 2.0
I have a 1998 VW Beetle that I had to install a new compressor, drier and condenser last summer. My problem is
that when I drive for over an hour, I stop feeling the AC blowing, if I crank it up to High I then feel it blowing. Now
the AC will keep blowing cold for a while but then I hardly feel it blowing again. If I turn it off for 15 minutes and turn
it on again, it starts blowing cold air. Does anyone know what could be the problem? There is also a bad smell that
comes from the vents when I turn the AC on.
Your help is greatly appreciated.
It sounds like your evaporator is freezing up not allowing the blower motor to pull air across it. Can you still hear the motor running when it isn't blowing? There can be a couple causes of this. Air in the system from improper evacuation, vacuum and recharge. Or the evaporator has moisture/mildew/mold on it that is freezing up when the evaporator gets cold and that can also cause your smell you are getting. The smell can also come from a dirty cabin air filter. These often go overlooked and are rarely changed. They filter the air that comes into the passenger compartment and can get dirty very easily. Has the vehicle's A/C ever been serviced?
Yes, I could still hear the motor running. As for the AC being serviced, I had someone install all the parts previously mentioned and the guy also did the evacuation, vacuum and recharge. Please note, this service was not done at a repair center.
