I did a search and while I know this is a common issue, I could not find the specific issue I am having.
The AC blower motor was coming on/off and pushing on the wire bundle would get it to start working again. I reviewed online and replaced the blower motor relay switch. I could see that one of the pins was melted. I looked at the wire bundle and it appeared normal, so I did not replace at that time. It worked for about six months, then started having the same issue. This time, I decided to replace the wire harness. When I attached it, the blower fan stays on, but I can not adjust the speed nor turn it off. The AC and the heat seem to both work. I then decided to replace the AC blower motor switch again, and that made no difference. It is still blowing at mod-high speed and won't shut off (hitting the off button actually increases fan speed).
I used butt crimp connectors, and question if the smaller low voltage wire might have too much resistance through that connector. I doubled the copper wire over so that it crimped tight, but voltage still will have to pass through the metal connector. Not sure if that would cause the issue I am seeing.
Appreciate any input anyone might have on this.
