Wwooaaahh that's the crash zone sensor!! *runn*

I'm not sure what to do next.

 

Yup, that's a crash zone sensor. Put that back.

 

Lol. Yeah i realized that earlier. Air bags are working.
Well i did went over the troubleshooting described on pdf attached by Mistang5L5. On page 101 and have to remove the center console in car to get to 20 pin switch for ohm meter. Then i saw that temperature started to fluctuate. Some times it will show correct temp and then started to drop down. It will turn a/c on when temp is correct and as soon the temp reading drop below freezing a/c will stop. This is getting annoying. Had to go to dealer now.

 

This happened to me recently. Replaced the ambient temperature sensor and still reading -30C. Forget the stealerships. I figured it out myself for free.

 

Hi, my AC compressor won't come on because my ambient temp is reading
--- icy so all I'm getting is hot air. I replaced the ambient sensor and that didn't fix it. I went to my small town mechanic (nearest dealership is 2 hrs away) and he tested the sensor wires and there's no power... So where do I go from here.. Test the AC amp or the AC relay power supply?
Where does positive voltage come from?

My boys come home from their dads next week and it's 105* degrees here, I need to fix it ASAP

 

It is most likely one of the wires from the ambient harness snapped due to age. This was what happened to mine. Resoldered the broken wire and now it is reading the temperature outside correctly. Hope this helps

 

Thanks for the quick response! I don't see anywhere that the wire is broken

 

changed ambient temperature sensor still reading -22
