Electrical Glitches

[mikester]

Went to drive the wagon the other night and had a few little electrical issues.
First the fuel gauge was bouncing back and forth for at least 5-10 minutes. It seemed to stop after driving it for a couple of miles.
Second issue was the fan. No matter what speed theres not much air moving. Hardly anything. Seems like the fan motor is only blowing on low. Could these things be from a grounding issue ?

Shocked to see 100 people looked at this and no replies. Anyone ?

If your fans are like my Intrepid fans, that does sound like a bad ground. If you take a ground away, my fans run on one coil, give them a second ground and they run on 2.
Motors should share a common ground but a separate positive, each fan has its own positive lead, so one for left and one for right.

The fuel gauge sounds like a rear ground, or the sender is going bad. Check your ground on your rear harness in the trunk and at the tank to the trunk floor braces.

Not a cooling fan. Its the heat/AC fan.
I'll take a look at the grounds at the back for the sender. Its a wagon not the coupe. Thanks for the reply !
