Mrkt280zx Posted May 11, 2010 Share Posted May 11, 2010 Alright guys. my wipers, radio, and blower motor dont work at all. they are functional by hot wire, but not with stock conections. I was told some sort of relay but one relay shouldnt control all that, a fuse should? Stock 1979 280zx Quote Link to comment Share on other sites More sharing options...

Another thing to check is a broken/pinched wires under the dash as it is easy to do if you are rushing to put it all back together I am fighting wiring in my car and the fusible link box was a mess in my car and I had no dash power as you stated. I replaced the whole box and magically I got power... Edited May 11, 2010 by blackice280zxt Quote Link to comment Share on other sites More sharing options...

I'm trying to resto-mod this thing. Maybe 400 SB swap it. Quote Link to comment Share on other sites More sharing options...
Mrkt280zx Posted June 29, 2010 Author Share Posted June 29, 2010 Alright so my wiring is solid at the fuse box and the fuses are all new and good. I thought it was a bad common ground but it isnt.... I'm at a loss again Quote Link to comment Share on other sites More sharing options...
Challenger Posted June 29, 2010 Share Posted June 29, 2010 Behind your glovebox there should be a set of 3 relays. Ignition, fuel pump and accessory. Check all 3. Mine had a prong broken off in the connector and I didnt have power to my radio, blower or wipers. Replacing the relay fixed it. Quote Link to comment Share on other sites More sharing options...
ThatGuyFromGates Posted July 31, 2010 Share Posted July 31, 2010 I know the thread is a little old, but did you figure out the problem? I just fixed my heater/blower motor electrical as well on my 76. Here is what happened: Checked the connectors going to the unit = no power. Checked the relay = no power. Checked the fuse panel, fuse good, power across both clips........but..... here is the catch. When I was checking for power on the fuse panel, by touching the top of the fuse itself, obviously it shows power across both terminals, thus completing the circuit. By taking the fuse panel off of the kick panel area, turning it around, the lead wire going from the fuse panel to the actual unit had NO power. Even though the fuse was good, if I carefully prodded the multimeter probe down to the actual spring-clip fuse holder, the hot side had power (of course) but the other side actually did NOT. Conclusion- took the fuse out, noticed a little bit of corrosion on the inside edges of the actual fuse holder/clip, lightly sanded them, popped the fuse back in, blower works. I did the usual electrical clip cleaning as said in most of these threads, but I didn't think to clean the actual fuse panel itself. May or may not work but I just wanted to pass it along just in case. Cheers, JK Quote Link to comment Share on other sites More sharing options...
Mrkt280zx Posted November 3, 2010 Author Share Posted November 3, 2010 Challenger- will definately try that as i have yet to get it going. we had a death in the family and the z had to be back seated. ThatGuyFromGates- Did remove the fuse panel and checked all connections when diagnosing before and all came back clear although I did clean all the terminal clips (a few had light corrosion) Quote Link to comment Share on other sites More sharing options...
