1995 850 T-5R Turbo sedan.My compressor doesn't engage. I need to jump it to add some refrigerant.
I can't find the relay. Where is it? HELP

 

Don't need to find the relay, you need to jumper the low pressure sensor. The sensor is on the return tube up by the firewall. remove the connector and jumper the two slots on the wiring connector with something like a paper clip.

Also, best to post your 850 questions on the 850 board directly. Its a pretty active forum and you'll find some help fast, plus look at the sticky's for some of the DIY videos (including charging an AC on the 850/70s)
