Ok need a bit of help its a 2008 ce300 maxforce dt driver said hit a bump and her clip lights quit working. Brought it in front clip lights dont come on with key on no other clip lights work have no tail lights and the light check wont work. Ive checked all the assembly's there good got my power probe out i can get all the lights to power up in the left cb panel using my probe. I changed the headlight 3 pack thinking the headlights and light check are all together there still no luck. The only thing that has been done to this unit is i changed the driver heater valve but there isnt anything around that i could have messed up i dont think but bus ran for 2 weeks after i changed that valve with no light issues. Thanks
Behind your stepwell heater is the body control module. Unplug all of the connectors, wait about 5 to 10 minutes and plug them back in and see if your lights work.
Just a update 1st replacment controller didnt fix the lights put a new clock spring and ts switch in didnt fix my lights or wipers not working ordered a second controller waited a week to get it programed and everything is fixed now.
