My Audi 80's air conditioning system is not working properly and it's getting very uncomfortable to drive in hot weather. What steps can I take to diagnose and fix the issue?
ReplyFirstly, check the air conditioning compressor belt to make sure it is not broken or loose. If it is, replace it. Next, check the refrigerant level using a pressure gauge. If it's low, refill it with the recommended type and amount. Also, inspect the compressor for any leaks.
Another common issue is a faulty AC compressor clutch. You can test it using a multimeter and replace if necessary. Additionally, check the AC control unit and wiring for any damage or loose connections. A diagnostic scan may also help pinpoint the problem.
If the air conditioning system is blowing warm air, it could be due to a clogged or restricted cabin air filter. Check and clean or replace it as needed. You should also check the operation of the blend door actuator to ensure proper temperature control.
