2003 PT Cruiser Turbo windows fog up on the inside with air or defrost on and there is a strong odor of anti-freeze. I replaced the low pressure recycling switch on the accumulator with no joy and I noticed some anti-freeze on the accumulator just below the switch as well as in one of the mount screws for the tubing. The coolant level is good, the heat and AC appear to working ok. There is however a whining noise coming from the right side of the engine. The belts and hoses are all good. Any assistance would be greatly appreciated, thanks.

SOURCE: air condition

Check the cooling system, particularly the radiator to make sure it is not partially plugged. Additionally, check the radiator fan for proper operation. If the engine temperature is running way above normal, some of the heat is transferred to the air-conditioning condenser, which causes the air-conditioner to lose efficiency. As for your question about a "limiter" switch, there is a high-pressure switch in the air-conditioning system that cuts the compressor out when the pressure gets too high.

SOURCE: windows fog up,small anti-freeze smell

try looking at the air filters. MIne was totally clogged with ****. No air circulaton equals foggy windows

SOURCE: No cabin heat.. windows fogged.. engine runs cold!!

chances are the heater core is clogged and wont allow proper circulation for the heater.i would suggest getting a new one put in and see if that dosent fix it for you.

SOURCE: 2001 PT Cruiser - blower and power windows stopped

Haven.t fixed it yet, but there is a bad wire or loose connection in a group of wires located behind the fuse panel. In the group of wires one of them is apparently the problem. When I move the wires the blower motor and power windows work, but they eventually stop again. I haven't had time to find and fix the exact wire that's the problem yet, it's not an area that I can easily get to!
