I recently did some work on the 300TD. I painted the gauge needles so I had the instrument cluster apart and put it back together. The car drove with no problems. the next time I took it out to drive to work the #2 fuse blew and the the #6 fuse. I replaced both fuses and now the #2 fuse blows if I turn on the turn signals. I took out the Inst. Cluster and the #2 fuse still blew so I ruled out anything related to the work I did when I painted the gauges. Then I found the passenger tail light half full of water so I repaired the bulb holder and now it is working again. The hazard flashers work so I think all the wiring is good to the lights. I also disconnected the power antenna and that had no effect. I replaced the Hazard switch and that wasn't the problem. The next thing I will try is replacing the turn signal relay for another $40 but the old one looks fine inside. There is an IC chip in it and maybe that is the source of the problem. I will let you know what happens when I replace it. ANY OTHER SUGGESTIONS? I ordered a Short circuit tester from Amazon to help diagnose the problem but I don't relish the thought of trying to find a short between the Inst. cluster and the flasher relay. All the wires are so inaccessible and bundled together. I am not sure where to look next. Any ideas?
