Cruise control problem
So I was driving on a trip the other day and I was using cruise I went up a big hill it downshifted and basically floored biggie, I does that all the time to try n maintain speed up a hill......only problem is, I'm going down the hill and it is still going wide every single time I turn cruise control on, it just punches it to the floor and won't stop until I hit the brake or turn it off...........what is wrong now guys

jeez snewt.

cruise runs off vacuum. there is the one box near the intake where it plugs in.
there are others. i would look for a vacuum leak ....

Re: Cruise control problem
if it is a vacuum then it would not work at all. i had that problem on my WJ. you also wouldnt have control of HVAC, only defroster. mine goes up to about 3000rpms while going down a hill at 65-70mph, how much is yours going up?

Did Toyota make WKs? :lol:

I don't know what to tell you. Don't use it and let the dealership look at it.
