W202 AC working well for only 2 mins, then
 

Hi,
I need your expert help once again for my 95 C280! My AC is working weird. When I start the car, the ac rocks for about 2 mins, really cold and working normal..then it goes off..goes to blow air thats the outside temp. If I shut the car off for 30 secs, and restart, the AC kicks back in for another 2 mins. (maybe its 90 seconds?)

Anway, I had someone try to charge the ac, and they said it wouldn't take the charge. The guy said it was 'electrical'...but thats all I got.

History: Replaced the compressor about 2 years ago...Typically I get a charge once a year..

Any ideas here. Thanks

Could be a loose belt or an evap temp sensor problem..

You can put that system into a mode that allows you to look at sensor inputs.

W202 where is the Evap Temp Sensor located
 

Thanks BD Doc for the diag.

Can anyone tell me where the Evap Temp Sensor is on the W202 C280 (95)? and
Has anyone ever seen images online where this is, and how to DIY.

Thanks!

David
