iainc Posted November 14, 2009 Share Posted November 14, 2009 (edited) Currently have a weird fault on a supra turbo (not mine). When heaters are on they work fine, untill the wipers are switched on then the heaters cut out till the wipers are switched off, then the heaters come back on. I have checked stalks and heater control on my car also checked fuses. only fault visable is that there is no intermittent. Any help appreciated.

Dave17 Posted November 17, 2009 Share Posted November 17, 2009 Does it all work when all the other electrics are turned on like lights and stereo? Quote Link to comment Share on other sites More sharing options...
iainc Posted November 17, 2009 Author Share Posted November 17, 2009 (edited) makes no difference what else is switched on, or if car is running or not. Edited November 18, 2009 by iainc (see edit history) Quote Link to comment Share on other sites More sharing options...

chrispot Posted November 18, 2009 Share Posted November 18, 2009 sounds like an earth fault, looking at the wiring diagram check the ones that are bolted to the front wings, i can not tell you exactly where they are, the wiring diagram just says front fenders, at the very front i belive, let me know how you get on, regards chris.

chrispot Posted November 19, 2009 Share Posted November 19, 2009 found it iainc so you can download it for yourself, i will still send if you want me to, when you look at the diagram you can see that the heater and wipers use "1B" earth point, i had a similar problem on a renault megane, just a thought try runing a seperate temp earth to wiper and or heater earth wires in the car to see if this cures your problem. let me know how you got on, regards chris, the site http://www.turbosupras.com/pages/pages/technical/jza80/a80tsrm.htm Quote Link to comment Share on other sites More sharing options...
