Noflers Posted October 9, 2016 Report Share Posted October 9, 2016 Took me quite some time, but I finally got all the wiring in my 510 sorted out and everything worked. Until yesterday, when I went to switch the wipers on and nothing happened. I dug around for a few minutes, trying other circuits before I found that the wipers turn on when I turn on the heater fan.The wipers and heater worked fine a couple days ago, now this, what's up?I'm sure there is a bad ground, or improper ground, but I'm not sure where to look first. Right now, I can only keep the wipers on low or the heater and fan together draw too much power and cut out, plus I only have one wiper :/ I need to drive in the rain! 1 Quote Link to comment

The heater isn't electrical so the heater has no draw on the system. Did you mean the wiper and the heater fan together 'cut out'? And what does 'cut out' mean?? Does it blow a fuse? Which one? 1 Quote Link to comment
Noflers Posted October 9, 2016 Author Report Share Posted October 9, 2016 I meant the heater blower motor. By cut out I mean the blower motor will keep going, but the wipers stop. Fuses are fine. 1 Quote Link to comment
datzenmike Posted October 9, 2016 Report Share Posted October 9, 2016 So it was working properly then? at one time, and then the wipers suddenly needed the heater on in order to work? Just curious.... If you have the wipers on and turn the heater fan off, do the wipers return to their parked position or do they stop anywhere on the windshield? 1 Quote Link to comment
Noflers Posted October 9, 2016 Author Report Share Posted October 9, 2016 Correct, randomly decided they needed the fan to be on... And no, they don't park when I turn the fan off, they just stay wherever they are. If I turn the wipers off alone, they park. 1 Quote Link to comment
datzenmike Posted October 10, 2016 Report Share Posted October 10, 2016 Well it's getting power from somewhere..... or getting it's ground from somewhere. Go to the wiper motor and find the Black wire. This is the ground wire so ground it with a jumper. Does this help? If different, what does it do now., 2 Quote Link to comment
Noflers Posted October 11, 2016 Author Report Share Posted October 11, 2016 I'll let you know tomorrow when I get a battery back in the car. You mean the wire that grounds to the motor body? It's a Mazda wiper motor if that makes a difference. 1 Quote Link to comment
Noflers Posted October 12, 2016 Author Report Share Posted October 12, 2016 Wasn't sure what you meant above, so all I did was pull the ground from the wiper motor body and clean it up (painted over from the reman factory), but it didn't help... 1 Quote Link to comment

Will report back when I try what you actually suggested. Quote Link to comment
Noflers Posted October 17, 2016 Author Report Share Posted October 17, 2016 Still not making any progress on this, all grounds seem good to me... Quote Link to comment
