Brake lights, blinkers, cruise don’t work when towing camper w/ headlights on
What is your question?
All lights work fine, as does the cruise, on van and camper until I turn on the headlights. I lose the use of cruise control, the blinker lights become flashers on both vehicles, the brake lights don’t work at all, when I brake the dashboard lights go off and come back on when I release the brake pedal, and the compass and temperature display are not visible.
How long has your 2002 GMC Safari had this problem?
Since I purchased the car 10/10/18

*Ground* the camper to the vehicle using jumper cables for the circuit - does that help? Need cables attached to a good clean metal ground on both camper and tow vehicle! You can do this test in the driveway. Note: simply hooking the camper up to tow vehicle does NOT establish a sufficient *ground* circuit!! Now - if the ground tests did not improve the issue - CAMPER wiring must be inspected, tested and repaired. Good luck!
