    Question K134 relay.

    I am going to order a relay from rock auto to try to fix some intermittent problems. My last major problem is the cruise control not
    working. Could that relay cause that or the EBTCM? or something else no blown fuses found.

    I can't say for sure if a failed EBTCM would just affect the CC and not the Speedo, TC, ABS, and Sport Mode. I would think it was all or nothing but I could be wrong. When my EBTCM failed I lost the Speedo and my Check and TC lights came on. Check your codes look for a U2108 before sending the EBTCM out for repair. Below is a page explaining the U2108 code in detail.

    Only one code and that's a P0155 for an o2 sensor. I really didn't think it would be an EBTCM, I am just at a loss the only other thing I think it would be is the
    switch itself.

    Pull the K134 relay and check for cold solder joints. The link takes you to a good K134 thread, pictures and everything.

    If you are having the radio issue where it won't power on in position 2 and only key position 1 upon shutdown, check fuse #10 for the aux water pump. This was our issue and not the K134 MF relay.

    Talking Re: K134 relay.

    Thanks Lizzys Cat, I changed the K134 relay and it fixed several small but annoying problems, radio, sunroof and fog lights that seemed to work when they wanted to. Now that's all fixed, just trying to figure out the CC inop. I pulled all fuses and none were blown.
