  1. :lurk:My 03 mustang cobra windshield wipers, gauge lights, power locks, and dome light stopped working. Brought it to a friends shop all the fuses are good and relays. Jumped the windshield wiper relay and the wipers worked. Replaced the windshield wiper switch and still not working :shrug: any ideas???
     
  2. I am not sure but I think all those items are controlled by the GEM or some other module? Maybe the GEM module is bad? Electrical problems are so annoying...
     
  3. use a vold meter to check continuity between the fuse and the switches and the fuse and battery. try jumping the negative from the battery to the component you want to check me and sure all is well. Most of those items have a common ground to the battery. If you can find where the fault is you shouldn't have a problem finding a break.
