yup, its been like this for a couple weeks now, and it occured to me i should ask u guys cuz search didnt show me too much except people changin out steering wheels. my cruise control switch still turns on and lights up the cruise light on the guage cluster. but when i hit the set button at say a highway speed, it just acts like i never hit it, it even makes a little click noise like it engaged, but the needles just drop as if i took my foot off the gas which is what i do.anyone know at what things i can look at to see where its malfunctioning? thanks, appreciate it

 

check your fuses and relays first. There is a bank of relays and fuses on both sides of the engine bay. If that is ok, check your taillights, if you have any bulbs out, I've heard that some cruise control systems (don't know if our maxs have this) will not work with a blown tail light bulb.
