I have a '92 525i and the check control message came on. Then the whole message bar went really dim, almost illegible. The air conditioning lights (recirculate and air) were flashing and I couldn't turn them off. No cool air was coming out. I checked my fuse panel and fuses #20 and 25 were burnt out. I replaced #25 no problem but as soon as I put a new fuse in slot #20 it burnt out immediately. I tried this twice with no success. Does anyone have any ideas as to what my problem is?
