Im working on a 1989 325i and can not figure out why Fuse 20 blew and now has no power.
Back story:
I was driving at 2:30 pm today with the a/c on and the fan on level 2. I smelled a faint burning smell from what seemed like the engine area and immediately fuse 20 blew. Installing a new fuse and measuring voltage shows no power at the fuse in the fuse box
What does not currently work-aux fan, a/c and blower motor.
I replaced the the aux relay in January-it has worked fine since then
blower motor and relay have always worked, same with the a/c compressor
Right now I have working everything else-power windows,mirrors ect. K5 and K7 relay should be fine. The wires in the radiator temp switch look fine as well as everything up front. Im going to pull the fuse box apart tomorrow and look in there-hopefully not a fire but who knows. Any other suggestions?
