intermittent signals,wipers and heater
 

Hello, I have a problem I have not been able to figure out. When ignition in accessory all systems work fine, when car running all these systems are intermittent. I have changed the load reduction relay,ignition switch and electronic control module to no avail. Please any help would be appreciated.


Thanks

Has anybody got any suggestions.I have been a heavy duty mechanic for 33 years, this has me totally stumped.

Is it when its running or when its moving that the problems start? If its when its moving, then there may be a loose connection somewhere, maybe in the fuse box.. Also is it the heater fan or does it not blow warm air?

figured it out
 

Thanks for the reply, I figured it out,before I went on holidays I installed new plugs,and went for a drive everything was good. When I came back and needed to use signals and wipers things went wrong. After pulling my hair out and ripping half the car apart, I've been a licensed heavy duty mechanic for over thirty years before then automotive. Wife gave me the idea to think out of the box,I decided to remove one of the plugs and realized I put in non resistor plugs which interfered with electronics. Change back to old plugs, problems went away.

Glad to hear you got it figured out!
