Weird Cruise Control and Radio Gremlins
My 2008 GMC Yukon Denali XL has started doing something weird. Randomly the cruise control drops out. I'll be cruising along and suddenly the cruise control drops like I hit the brakes (I didn't). It re-engages fine and goes along for a while and then does it again. Sometimes it will do it when I use the turn signal but not always so that could just be a coincidence.
Then about a month after that started, the radio will cut off randomly for a second or two. Screen goes blank. Then it comes back on. Sometimes simultaneously with the cruise control dropping out, sometimes by itself.
Sounds like an electrical wiring problem (bad connector maybe) but the systems are so unrelated I don't know where to begin to look.
All suggestions welcome.
