all my power windows stopped working simultaneously, fuses are good what's the most common reason other than them?

Asked by Jul 28, 2017 at 01:02 PM about the 1993 Audi 100 CS Sedan FWD

Question type: Maintenance & Repair

Check the fuses under the hood and on the left of the dash, but all my Power
windows are dead, not only at the main driver's switch but at each door switch
as well. What else should I check?

the power windows normaly don't just operate off a fuse. They also work off a small silver relay you can often find under the dash. maybe try replacing that and see what happens. wrecking yard should have it and they might jsut say take it for no charge.

THank you, Today I found that none of my climate control stuff is working as well. The Outside temperature sensor, and AC, both quit, as well as my turn signals and wipers. I don't believe a 1993 100CS has a climate control module and at the same time, I'm not so sure all these power accessories are connected to the same relay. Any ideas?


well with the way the cars were designed they often are. seach around for a relay document and see if you can't figure out which one controls these things. alternativly try finding 2 relays that are the same in the car and swap them around if you can't find a relay to buy that is. alternativly i would look at the wiring if all the relays turn out ok. casings can get britale over time and break causing shorts, wires corrode at the plugs and cause bad connections from moisture build ups *i personal call older audis the Hot Box due to the amount of moisture in them * start at the fuse box wireing and follow it to the ecu for signs of brittle wires and breaks as well as corrsion.
