But the proper fix is to put a ground from the battery [-] to the chassis, and a wire from the chassis to the engine block. Make sure the chassis ground for the wiper is good too as well as checking the other grounds.

Notice how most battery grounds have a extra wire? this extra goes to the chassis.




The Ground issue may not be your only problem but it is a good start. Especailly if you know you do not have a engine and chassis ground.

Allen Here's a novel idea, let's not throw a bunch of parts at the car hoping it will fix the problem and instead spend a little time diagnosing it first. Life was a little easier when I was just a wrench.
