hey guys my 1990 4dr 4.0 cruise control refuses to work. ive replaced the vacume hoses, the actual switch in the steering colum and checked all the fuses. any ideas? any help apreciated

 

Is the check engine light on? I say this because I had that problem and it was a bad neutral safety switch. Cleaned it, put in new grease and it works fine now.

 

no man, check engine light is not on and i cleaned the nss when i was having tranny shifting problems. everything works perfectly other than the cruise control

 

anyone? help?

 

actauators are problematic, as well, check your brake light switch on the brake pedal shaft. if its out of adjustment, or shot, then you'lle have no cruise

 

sorry what does that look like?

 

i apreciate the help

 

come on guys??

 

if this was bad he wouldnt have brake lights either... theres only so many parts to the cruise... the switch... the motor... the wiring... the fuse... if youve replaced the motor and switch then is say wiring... or make sure its hooked up in the first place... lol

 

ya ive traced the wiring and everything is hooked up. i do have brake lights lol but one thing weird is you can take it out of park even though your not pushing on the brake pedal, that have anything to do with it? lol sorry guys i dunno anything bout these little things, ive had 5 jeeps and this the first one that has had cruise!

 

i just looked, there is two switches on the brake pedal, the upper one is white with a little piston comin out of it with two wires and the lower is black with 4 wires. any ideas?

 

i was just about to ask if there was two of them... i dunno man... possible... none of my jeeps have cruise either... lol

 

the lower one is for the brake lights and the cruise control, the non cruise control ones only have 3 wires. dont know what the top one is for. like huntingman said, i have had a few jeeps and non of them had cruise control, cause you cant cruise up a hill or through a mud pit at 7mph!!!

 

ha i dont need it! just thought if it was somethin dumb it would be worth looking into. thanks for the help though guys!
