    Hi Everyone,
    I have a 1979 K5 Blazer.

    The other day my wipers stopped working, I am pretty sure it was caused by a blown fuse. (I accidently tried to use them while they were frozen to windshield)
    A lot of the print is rubbed off my fuse box, and I cant read where the proper fuses go. Does anyone have a diagram or know where the wiper fuse goes/ what it is labeled on the box?
    Any help would be greatly appreciated! thanks!

    thanks for the link, It worked for me.
    Hmmm. I found the fuse, it tests to be fine. The link you gave me said there was also a 30A circuit breaker specifically for the wipers, any idea where that would be? (Im guessing that is where my problem is)

    Glad it worked for you...thanks for letting me know.

    Unfortunately, I do not know where it would be located but someone should be along soon who does. Good luck!

    Hey Cep, welcome to the club. I'm not sure but I don't think the circuit breaker is your problem. Circuit breakers are meant to break when there is too high a load on a circuit (wipers stuck & w.w. motor overheats) then after the c. breaker cools, it makes connection again & continues this cycle untill the short or the high load dissappears from the circuit. If the c. breaker stuck closed, (on) the fuse should have blown to protect it. If you are sure the fuse is good, then I believe the problem is somewhere else.
    How long were the wipers stuck to the windshield while the wiper switch was on?
    How did you check the fuse? Just to double check your fuse, I would take a fuse from another spot & try it in your wiper position
