Where do I look to identify th' fuse boxes & relays on th' passenger side of th' 108 4.5 firewall. Compressor/air conditioning works with hot wire jump to compressor clutch. Any & all help appreciated.

Thanks, Jim

I believe the AC fuses are the ones on the far left of the bracket, but I would simply replace ALL of them, cleaning the holders when doing so -- if one is bad, the other's aren't far behind.

You could also have a bad fan switch, it controls the main on/off function of the compressor, or the temp switch is bad. You will probably have to pull them to check. Tmep switch should click on and off as you rotate from full cold to warm.

Just replaced mine, 8 in all. four little black caps firewall on passenger side, easy job.

but they are also pretty corroded. Tomorrow I will clean things up and then check th' dash reostats/switches. Sure was relieved when th' 12v jumper to th' clutch produced cold air inside th' car.... Gonna try to get this rusted thing to Atlanta in October so you fellers can tell me how to save it(rode my Valkyrie last year, drank two homebrews and was schnockered all th' way back home).
