Cruise controll not working
Here is a posting from another site, I suggest read it...
I posted on Thursday about my 2001 Cherokee Sport - thought I would give
an update on here that may help someone else.
After thinking about things alittle more -
* All air going to defroster mode
* Cruise Control not functioning
* Check engine light on. Code decoded as "small vacuum leak"
Well, I had been researching and know that the air blend doors are
vacuum controlled. I discovered that the Cruise Control is also vacuum
controlled. This along with my check engine light "small vacuum leak",
led me to believe that all are related.
As this is my wifes vehicle, I am not sure if all happened at the same
time or not. As most know alot of women do not pay attention to
anythingto have details to provide the husband in proper diagnosing -
other than "it dont work - fix it"
I pulled it into the shop yesterday and just looked under the hood not
knowing where to start. I mean, a vacuum leak doesn't flash a red light
saying fix me... So after another cold beverage, I started pushing and
pulling on vacuum lines, disconnecting and blowing in them. Nothing! Ok,
another cold beverage ... I grabbed another line and was disconnecting a
line from a t-fitting and the whole thing came loose... the end was
broke - WaLa ! It was the vacuum line that runs inbetween the passenger
fender wall and the battery behind the headlight. What had happened I
assume is, because the tie that held it to the fender was broke, is when
I changed the battery last year, the line was in the way and broke ? So
I made a hose patch for it, got it all back to gether and checked it
out - No more check engine light, got air in all directions!
So, I tell the wife to come out and I need her help. I told her to get
in and start it and wait for my commands... She gets in (I set the ac to
max), starts it and looks at me, I just stand back for a sec - finally
she realizes she has ac blowing in her face ! Then I had to point out
the engine light... I took a drive and the cruise now works as well !
Well, I got lucky ad found where my vacuum "leak" was and got it fixed.
Time spent researching: 2 hours
Time spent repairing: 30 minutes
Total cost:.25 cents (tape and piece of hose)
