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.

Re: K134 relay.
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.
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.
