Dorman 902-020 Outdoor Air Temperature Sensor Compatible with Select BMW Models

I buy these bad boys all the time and cut open the power mirror harness on HD trucks/ peterbilts mostly and retro fit these sensors in to make the check engine light go away for ambient air temp sensor codes when the original sensor fails. Better then replacing the $300+ harness.

When I bought my 2004 BMW 325i it was winter time and I didn't check the AC until next summer. I was issues and turned out, the previous owner ran over a parking bump and ripped the under plastic cover along with this sensor which made the AC not work sometimes.Installation was easy, I still don't have a replacement plastic cover where this normally gets mounted to so I just installed in a near by place that would still work.AC now works great! It's been a while and I have no issue with AC. If your AC gets cold air and randomly doesn't, then it does and some days it don't.Look at your ambient temperature, if it's saying 90+ all the time or negative low number, chances are your sensor is bad or has been ripped off. Cheapest way to fix your AC without a trip to the stealer!!

Includes the pigtail. This is great since broken wires or torn off sensor is the most common failure mode for this item.

My wife's BMW 323ci was showing -40 and her AC didn't work properly. I realized that the ambient temp sensor had been ripped off somehow. This replacement was just the cure. I located the existing wires, connected the new wires and the sensor and secured them all in a safer location high in the bumper and now the AC works like new. BTW, it took about 20 minutes to make the fix and that's just because I'm anal, it could've taken way less time if you just throw it on there and go.
