Car Forum / Mercedes-Benz Cars / September 2004300 SD Hot Relays!
Attempting to get my recently acquired car road worthy and have encountered what to me is a strange problem. Several of the relays in the fuse box get hot... real hot... can't touch hot if I leave them inserted. I have several things disassembled at this point and am not sure which relay goes to what. If I let them cool and plug them in I can get all four windows to work. Let them heat up, and the driver's window will not work! Any thoughts/ideas/help? I have ordered a couple of relays in the hope that will fix it. If not, I will have spares... Wingnut Windows motor do take alot of amperage... which will make it heat up fast... I would check the fuse first... make sure it is the right fuse specified by MB... not too high. Then I would check the wiring harness at the switches to see if any tampering. > Any thoughts/ideas/help? I have ordered a couple of relays in the hope > that will fix it. If not, I will have spares... I would check the electrical systems voltage while running. See if that is too high? Marty PS could also be a partial short somewhere. Thanks for all the responses. I will try some of them out this weekend when I get back to the ranch. > Attempting to get my recently acquired car road worthy and have > encountered what to me is a strange problem.
