I’m installing a remote start in my 92 XJ and I found this connector charred. It’s the purple wire which I believe is the accessory/blower motor wire. How worried should I be about this. Heater works fine
The blower fan draws its current right through that connector, and it can be pretty high (as much as 20 amps on an old blower fan). So any resistance can cause a lot of heat. Clean up any metal contacts as best you can so that the resistance is as low as possible. I would also, if you are able, measure the amperage draw on the blower fan at its various fan settings, particularly the high setting to see what it is pulling. If it is pulling more than 20 amps, I would encourage you to put a new one in. But even new ones, pull quite a bit. The best thing you can do, hands down, is to limit the time you allow the blower fan to run on high. Run it for a few minutes on high, but get into the habit of turning it down a notch after that, it significantly reduces the amperage draw if you do this (one notch lower will almost cut the amperage in half), and will help that connector last a lot longer.
