I've spent hours searching the forums for my problem, the blower was working on defrost only now it doesnt work at all. The blower works fine bench tested it and jumped the green/red wire from the resister on the fender to power and it works fine. I soldered the acc even though I tested it in my other 85 300D, so the acc is good, cleaned fuse (it wasnt blown). Is there a relay? I looked behind the glove bow and only saw the one for the EGR It seems like a relay issue this is for a 85 300d thanks Mike
