Just at some times?
Or all times?
I can scan the schematic and psot the pdf if you want to look at the diagram and try to figure out the various culpirts.
I'd have to look, but I do think each side is fed from seprate wiring harnesses; i.e. passenger side and driver side.
I think that because I cleaned all those wires, tie wrapepd, and loomed them proper like, instead of the wild wiring the factory left.
But can't say for sure without looking and reading the schematic.
