FSR issue..

So my fan was on the fritz and after digging on the forum it lead me to the FSR. Rather then buying a new unit and hoping it was right i picked up a second hand OEM unit from a low mileage totaled 3 series.

After ripping into my dash and removing the fsr from my heater core i noticed it was impossible to remove the electrical connection. After some swearing, prying and yelling i finally got it off only to find some melted connections.

Just as a quick test i placed the new (to me) fsr into place and connected the semi melted connector and sure enough everything is working fine.

The problem is now im left with a tricky situation. Do i leave it and hope that the melting was due to the old fsr (which was obviously replaced at some point, it was a later bosch unit). Or do i try to track down a new connector and splice it in place?

The last option would be to drive a few days without my glove box in place and make sure there are no electrical issues.

Suggestions?

I would highly suggest getting a new connector and replacing it. Solder, shrink wrap and fix that ****. Melted electrical connections are just asking for your **** to burn to the ground..

It probably got super hot and melted it.. change it asap.

Its not so much a "should i replace it" thread but more of a do you think its safe to use until i source a new connector.

There is no metal on metal contact between the pins just some melted plastic. I replaced the fsr so the unit that was obviously getting hot is gone. I figured that the fsr should keep the pins on the connector in place and prevent any metal on metal contact. I should also mention that none of the wires are melted either, just some of the plastic around the connectors pins.

I would say yes you're safe for now, but I would move sourcing a connector high on your to do list. Anything melted electrical is sketchy IMO. You should be okay for a while though. Just keep an eye and a nose out for anything amiss.
