Just wondering if someone could help me if you have a diagram of the fuse box for a 1990 F150. My windshield washer quit working and I checked the line to make sure it was not froze. The cover is missing off my fuse box and I don't have a manual to see which is the fuse. I can not see any indication on the fuse box itself. Any help would be appreciated thanks

 

The washer and wipers are on the same fuse so if your wipers still work then it's not the fuse. Plus, there's only like 15 fuses, just check them all. There is no listing for the wipers on my fuse box cover, but mines an '87.

 

Mine is a 93 but it is position #2 which is on the left side and it is a relay (metal housing) not a regular fuse.

 

Thanks for your replys,the wipers still work so I guess the fuse is not the problem. The hose is clear but I did get some ice out of it.I'll wait till it warms up a bit. Dang cold here in Canada
