Car Forum / Volvo Cars / December 2005'96 850 wagon - No cabin fan
On my '96 850 wagon, 5spd, the cabin fans no longer run. When I turn on the climate control (heater, defroster, etc) the re-circ and A/C light just flash. I have the computerized climate system. The manual says is that the flashing lights indicate a fault and I need to take it to a technician. The local Volvo shop can't look at it for while. Any thoughts, suggestions? Right before I started having this problem I did notice that the fans sounded louder than usual. > On my '96 850 wagon, 5spd, the cabin fans no longer run. > [quoted text clipped - 9 lines] > Right before I started having this problem I did notice that the fans > sounded louder than usual. This indicates a code is stored. Often this is caused by the heater fan motor seizing up. The climate computer monitors the current the motor needs, and if it gets too high (indicating a failing motor), the motor is shut off and the lights flash. Of course, you should have the codes read to make 100% sure, but the fact that the fan was louder than normal makes me think a new fan motor should cure your problem.  SignatureMike F.

I'm not sure on a '96, but you can read the codes for the climate control on the '95 by putting the test lead into the #1 socket on module B (the one to the right). The fault codes are given on page 3-10 of the Haynes Repair Manual. You might also find them at Volvespeed.com.

Starting with the '96 models you have to have the special equipment to get to the error codes. >> I'm not sure on a '96, but you can read the codes for the climate control >> on [quoted text clipped - 6 lines] > with the '96 models you have to have the special equipment to get to the > error codes. That makes sense. 1996 was the first year OBD-II was required in the US so it became pretty common, and the spec didn't call for the owner/operator to be able to read the codes.

I suspected it was something like this. Any idea how much this should cost? Just so I know before the mechanic gives me a quote. Thanks for all the help! >> This indicates a code is stored.
