Hi BMW Owners,

Lately I have issue with Air Cond Cool & Warm Intermittent issue on my E46 N42 model.
I have check with Car Air Cond specialist but he suspect wiring. The guy checked and advice me to service the Air cond.
Earlier i have blower noisy issue. I told the guy to change it.


Parts I changed: -
1. Blower
2. Compressor
3. Air cond filter
4. Blower motor resistor
5. Filter (above Engine)
6. Coolen filter (near front bumber)
7. Gas fill + Service


After Change & Service, at time it was cool and I thought the problem could be compressor. When drive back home, problem came back.
The aircond guy, couldn't identify the issue. but he keep saying could be wiring or ECU problem.


I went to one mechanic, he solve the issue in 10 minutes. He check and change the outside aircond temperature sensor.
Air cond cool working perfectly fine.
I learn my lesson. Always go with basic before go advance.
Any issues with your BMW Car, check which sensors is not working before change the parts.


Thanks & Regards,
TJ
