    AC Fuse

    Back in 2003 while we were visiting Florida, my wife bought me a 1990 Festiva to tow behind our RV, the car and tow rig was cheaper than a tow rig by it's self. Fast forward, given gas prices I dragged it out of storage, spent a small fortune getting it through California smog and am enjoying the hell out of driving it.

    When she bought it, it needed AC work, we had a new compressor put in and a 134 conversion done. It never worked right and it appears that the engine fan (manual tranny model) should be coming on when the AC is fired up. Well, I blew the darn line fuse while trouble shooting it. The manual says it's in the line from the ignition switch to the compressor relay, but I don't see it anywhere. According to previous posts this may be a dealer add on system as there are two relays, one on the firewall and the other on the passenger side fender well on the way to the compressor.

    Any suggestions....

    The fuse on most of the A/C's I have seen are on the right side of the gauge cluster near the blower motor under the dash. Is that the fuse you are looking for?

      One of thoes relays should be for your fan. (fat Yellow wire? maybe with a stripe?) The power chain cascades throught the relays and pressure switch. So if one is not working everthing down stream stops working. Does your fan work when the car normaly gets hot?

        Air cond. fuse

        The fuse on my 89 was behind the insturment cluster also, it was hard to find, but that was the problem, it was an inline fuse, but a flat 10 amp fuse.

          Air cond. fuse

          Well, thanks all, I found the fuse holder, somebody had stuck a 30 amp circuit breaker in it, checked good... Back to the drawing board. This dealer added air is a bit of a problem, none of the components seem to be where the service manual shows the factory air to be.

          Does the dealer air have a electronic control box or a thermostatic switch, if so where are they and what's a proper check for them.....

          Thanks, Jim Bauer
