A/C wireing problems
Posted: Tue May 29, 2012 6:40 pm
Hy folks. Say, I've been workin' on my 93 SST. Weather's getting warm, so I decided to service my A/C. The clutch wouldn't engage from dash controls, so I jumped power to it and it worked fine. So, slightly cool air, sight glass showed lots of moisture, so I evaced. it flushed it, pulled 23" of vacume on it for about an hour,and switched to 134. Still jumping it, the thing makes 40* @ ctr. dash vent. Nice. But, I've still not been able to get dash controls to work. Checked all fuses, replaced both relays, no help. I pulled the glove box to look at the cut relay, and t-stat, but you can't see much. Don't know where to go next. I'm powerin' it thru a rocker switch on the dash, but I don't like bypassin' all the saftey devices, and temp controls. Ideas? Thanks, Steve.
