1995 Volvo 850 cabin blower motor has failed x2

Hi,

I have a 1995 850 turbo sedan and the cabin blower motor died (I ignored dry bearings for too long). I bought a replacement and installed it and it worked fine for about a week. Yesterday, I got in the car to drive home from work and the two small circular red/orange lights under the REC and AC switches on the climate control console were flashing and the new blower motor was no longer working.

There is a click when I try to turn the blower motor on, so I think the relay is still good, but I am at a loss as to why the new motor is no longer working and I really don't want to buy yet another one and install it only to have the same thing happen.

I would greatly appreciate any help!

Thanks in advance

The power transistor pack that determines can speed can die and give you both the failure of fan and the flashing error codes. I believe you can read off climate system errors under hood or maybe by triggering the ECC to show. Odds on a 1995, search the VRD on how to do this

Get the code read.

I read the code. It is: 418 No control signal to blower fan power stage.

Is this likely the faulty part? https://www.fcpeuro.com/products/volvo- ... 50-9134932

That is the part. Unfortunately they are unique to 850's with ECC control so I don't have one I could send you. You could try a junkyard or Volvo specialist in Vancouver, or even Chapman Motors Inc on Vancouver Island. I have never had a bad part from them over many years. Not the cheapest but cheaper than new!
