Hi decker1
I would change the
Power window fuse just to be sure that it is, in fact, good! I would use a multi-meter set to DCV (low volts scale) to check the fuse in question for voltage with the key in the
ON position. If it turns out the the fuse isn't the problem, I would do a
Master Reset on the
Main body ECU Compu Network.
Look in the main Rly/fusebox under the hood, and locate the
'Short-pin' in the top row of the fuses; it looks like a WHITE fuse but it's not. It feeds the dome lights and the MB-ECU and 25 related ECU's! This is there to prevent a battery drain (by a door being left ajar, or the 26 or 27 ECU's drawing current) while the truck is being shipped from the factory to it's dealership destination!
Pull that short-pin out and leave it out for a minimum of four hrs! This will
RESET the ecu's to their factory settings! When you reinstall the short-pin, the radio pre-sets will be lost, and the Instrument panel "Compass" will need a
"Circle Calibration", confirmed by a Blinking Dot adjacent to/left-side of the direction icon e.g.,
.N!
Instructions for a compass 'circle calibration' is in the manual (procedure determined by the Trim level)! Let us know how you make out with the master reset and circle calibration when completed!
'Best to you',
