Hi All,

My 91/750T/185Kmile heater blower isn't running - just as we are in the thick of winter here in CT! Hoping you have some ideas to look for because I'm getting cold fast!

Situation:

- replaced the blower last year/this time (new from FCP)
- has been running on position 5 only since last fall indicating heater resistor pack failure per FAQ
- today doesn't blow at all (but car runs/temp normal)
- checked Heater 30A Fuse #6 per diagram and it looks ok
- I have not pulled the CCUnit (though did replace with good/used 2yr ago)
- I have not pulled the fuseblock to look at underside

Is there a Heater Relay somewhere I'm missing? I couldn't find it on the FAQ diagrame and have searched the forum - no mention save for seat heaters. If there's one hidden away I'd love to check that (I've been repairing those under the hood, could it be one of them)?

Any points in particular you'd suggest checking?

Lastly, is there a USA source for the heater resistor pack other than the dealer (FCP doesn't seem to have them on their website)?

Many thanks in advance!
