A/C, Radio 7 Fuel Pump Problem - Bad Ground?

5

Asked by Jul 12, 2016 at 06:13 PM about the 2006 Saab 9-5 2.3T

Question type: Maintenance & Repair

Last week, my speakers would output a whining noise directly correlated to the gas pedal while driving but
everything else worked perfectly.

I brought the car in to get rear tires replaced and a front alignment. I left and the noise was gone.. However,
now my AC blower blows at like 50% and sometimes when I start the car, it putters up and down and then
turns off. Radio also doesn't seem to get as loud.

From everything I'm researching, this appears to be a bad ground somewhere.  As in components are not
getting enough voltage.

Considering all of these things are affected, any clue where I'd begin to fix the wiring/ground issue?

The shop I went to didn't want to acknowledge they may have caused this in any way. It does seem like it
shouldn't have but I doubt it was a coincidence that this happened immediately following the work they did.

Any ideas? Thanks!!

Check ground cable from battery to the frame, obviously it's getting good ground from battery to engine otherwise it wouldn't start. If everything looks ok, go to ur local auto parts store and get yourself a wiring kit and add a #12 stranded wire with a ring terminal on each end from battery negative terminal to the firewall and see if it helps.
