Did your turn signals just quit or have they never worked?

 

[89XLT]

Turn signals work perfectly.

Turn signals work perfectly.

My bad. I mean the wipers.

 

[89XLT]

They haven’t worked. I have power at the fuse block. Not after the switch in the engine bay.

When you push the washer, does it work? Both washer and wipers are part of the multi switch in the column.

 

[89XLT]

No. Neither functions at all.

I would suspect the multi function switch in the column. They are easy to replace.

Did you put the new sending unit in because it alway registers full or did the problem come after the new sending unit?

 

[89XLT]

It’s after the new unit was installed. Before it was registering empty.

 

[tw205]

I would suspect the new sender is the wrong one. Pre 89 low ohms was full tank. 89 changed to high ohms full. If you can take the connector off the tank and put a ground on the yellow wire it should make the gauge go to empty or even past empty. The yellow wire is the ground to the fuel gauge.

Genius! I’ll try that tomorrow! Thank you!!
