#1 fuse under hood blows everytime I put a 7.5 fuse in. its a 91 850i auto. appreciate any help.
wipers still not working

Here is what F1 feeds
-
Here is the wiper circuit from F1-only 3 relay coils. You could pull them to isolate the wipers from the climate control.

Digging further. F1 powers the Aux water pump and both heater valves directly.
Unplugging the pump would be a good test too. It is a likely culprit.
Be very careful that you don't put pressure on the hoses coming out of the pump. If it is original the fittings are quite fragile due to age.

huh?
Should i not drive the car until this issue is fixed. Does this mean my aux water pump does not work and heater valves? I also took out #15 and #22 since thay all had to do with the wipers, should i put them back in and just leave the #1 fuse out since it does not work. If the pump is the culprit what is the next step in fixing? Thanks Terry

Aux water pump is just the heater circulation pump. If you don't need the heater you can unplug it.
You probably should do that just to make sure that it is the problem blowing the fuse.
Relatively Easy DIY or about an hour in the shop.
About $125 here http://www.autohausaz.com/index.html may be more or less elsewhere.

Thanks Terry . I will take it to the shop and have them unplug and test to verify problem. Sounds like a good start to me. Ill update after visit.
