Default lights ?

New to the forum.. I had the a/c evap. replaced in my '99 Grand Cherokee .Now if I try to run the wipers and the headlights at the same time , wipers slow or stop. Also if I open drivers door the rear window solenoid opens. I replaced multi-switch, no go. Have checked for shorts the best I can. Any help would be greatly appreciated. Frank

Check the ground cable that goes from the battery terminal to the body. You definitely have a bad ground someplace.

Well you need to get in there with the old multimeter and field service manual schematics and do some verifications and troubleshooting. Keep us posted.
