    Could possibly be one of the ckts that the relay controls is drawing too much current. Not enough to blow the fuse but enough to burn up the relay over time. You could try pulling all the fuses on the ckts connected to k134 and see if the relay lasts. You could also check the current draw on each ckt.
    Certainly could be something else but this is one direction to take.

    Re: K 134 multifunction relay

    Hello All: Can the contacts on the relays in the K134 be cleaned up? I'm guessing that the contacts can accumulate crud after many years use. I've had problems with mine, and checked all the soldered connections on the back of the board. By the way, if one needs a new K134, where can they be purchased from?
    Regards, Brian

    You can get a new one from Rockauto.com for $53, p/n 90494163. You can try hitting all the solder joints with a soldering iron in case there's a cold solder joint. Not sure if you can access the contacts to clean them or not. You can also try a used one from the junkyard for like $5.

    If im not mistaken I cleaned mine by spraying electric clean. I sprayed alot , kind wash it out. Electric clean was in red can. U can buy it any automobile part store or in walmart, its cheaper there
    Since that I don't have any issues. It did cut of on me few times since pass year. But thats not a big deal

    The trunk just went out tonight.... been having problems with the radio cutting off for a minute or two at a time, Will this relay fix the radio issue as well?
