Fan only works on high (4). Air conditioner button engages but does not light up nor does the air work. Replaced the "sword" with no luck. Anyone have experience with this? Thanx
ya the sword is the resistor-thing for diff fan speeds? Hmm I wonder what else could be in the circuit - you should be able to find an E34 ETM on wedophones, getting into the weeds with that might help trace through possibilities. google wedophones BMW, there's a page buried there with old owners, service, and ETM's.
thanx for the input. as it turns out if fan blowing high (4) the sword is out of the path so cannot be the issue (from bimmerfest post). replaced with two different swords so i will believe. have not found any other posts that remedy the situation. as mechanic said "will have to muddle through".
