'92 535i. Fan is becoming Intermittent on all but high, when it quits, I can run on high for a short while then it will work on slower speeds again. looking at the wiring diagram, there is a thermal limiter located within a resister box, could this be failing and is this resister box the one located in Fig. 4 pg 640-2 of Bentleys. This would also give me a -2 or -3 system which is my feeling. Looking at wire diagram for 89-90 it shows a final stage unit, described on page 640-2 as an IHKR1 system.
Finally, anyone know a price on this part?
Thanks in advance.
