84 300zxt electrical fun
Recently the digital dash in my 84 300ZXT quit working.turn signals,warning lights,etc all still work but no joy from the digi dash of 80's awesome-ness.Before it would sometimes not work and hitting the dash would make it come back on so I was thinking it was the power unit being faulty.So I took it out and resoldered all the pins but still no joy.So I checked the fuses and all of them work as indicated by my multimeter. So before I go track down a good power unit or convert to an analog dash is there anything alse I could check out?
Also the electronic climate control has never worked for as long as I have owned the car.While I was poking the fuse panel with my multimeter I discovered that there is NO POWER to the Aircon Blower fuses.So I checked the relay and checked for power/continuity at the terminals and everything checks out.If I run a jumper wire from one of the many wires supplying power to the fuse panel and run it to the aircon blower fuses, I can turn the climate control on and it works, hardware failures not withstanding (the heater core leaks and was bypassed by the previous owner,and I deleted the AC). So there is a break in the wire that feeds the aircon blower circuit somewhere between the relay and the fuse panel,any areas I should check in particular before I say "screw it" and run a jumper lead from a wire supplying the fuse panel to the air con?it would be awesome to have a functional defrost even if I don't have any heat just to keep the windshield fog free.I can bundle up its just hard to see where your going when the window fogs up at less than 20 mph.
