My truck has been running fine.....but when I was going to go home the trucks low coolant light came on, the high beams and low beams came on at the sametime ( but the lights had a dingy look to them). But when I turn my high beams on with the the switch the driver side goes out all together and the passanger lights up. But also the a/c dosent work either. I have figured out that the a/c works when you turn off the lights manual. Help please...
