1978 Rear Whiper Relay/Fuse?

[lada03]

Hello
I have a 1978 930 that has a dead rear wiper switch. Its frozen and wont push down

I replaced the switch but the rear whiper still wont engage.

Question: does the rear wiper have its own relay or fuse? If so, where is it?

I will check the connectors to the rear wiper motor as well

Thanks for any input/picture of relay/fuse location

The rear wiper has 2 supply's , one is connected to #30 on the rear fusebox, the other one is coming from #15 on the front fusebox, you can easily follow the 2 separate loom that lead in 4 wires to the switch. (red-black and brown-white = tunnel harness) and (red and brown = supply harness)
The wiper motor harness on the rear decklid has 4 wires (brown = ground, red = supply from rear fusebox) (red-black and brown-white are connected with the tunnel harness inside the engine bay) I suspect the fuse in the back is blown.

Thank you, will check the fuses

Are you refering to one of these 3 fuses in the rear?

[gerakroo]

Yes !

[lada03]

I checked both the front and rear fuses

Both looked good

Maybe motor is dead

Rear whiper motor gets hot

And one of the connection tabs
Broke off




If motor getting hot, then brocken? Need new motor?

Maybe the motor itself is still good, except for the broken spade connector. It may get hot when powered if the wiper mechanism is seized.

Looks like the motor is gone

I removed the cover. I was able to turn it by hand but its all gunked up into one ball and doesnt move under its own power

Anyone have a spare motor?
