Thread: Puma blower fan cuts out intermittently

I am pretty sure the AC itself runs (can hear the compressor cutting in), but as I say the fan does not. After a few minutes of driving, it will sometimes start for reasons known only to itself (a loose wire re-establishing contact? ) but then again it can also sometimes stop while driving (same wire coming loose again?).

My thoughts are to start at the fan connection in the engine bay, AND the dash switch - the fact that it doesn't care about the fan speed or switch-on method makes me think it's an earth wire somewhere...

Has anyone had this before, and/or have any other suggestions where to look?

Thanks in advance!

Had the same problem in our 2012 90 two years ago. Had to replace the whole fan unit, fixed it and no issues since :-)

Looking like my problem is the same as travelrovers... I can find what I think are correct voltages at the resistor and the fan motor when it's switched on, and I ran a direct lead to to the fan to try to get it to spin: no joy. So, I think dead fan.

I've pulled the fan out: not fun. The LH inner guard liner/ arch flare needs to move, plus the power steering reservoir/ washer water reservoir/ air intake duct to be able to extract the fan motor. It's out, so will now order a new one. If only LR had allowed a bit more room between fan box & wing top, or made the fan box mirror image for RH drive cars... Argh. Not looking forward to putting it all back together.... that guard liner is a pig of a thing, especially the bolts along the top of the wing.

OK, enough whinging, credit card time.

It could be that your ignition switch is on its way out. When the fan is not working, do you have radio and power in the lighter socket? If not, then it's most likely your ignition switch.
