While driving if I push in the cruise button, it goes in but wont engage. Why? Help will be appreciated.

 

Does your speedometer work? My cruise wouldn't work while I had the speedo/vss unplugged.

 

first thing i always check is the cruise button that gets pressed by the brake and clutch pedals.

if they arnt pressed in when the pedal is up, it always thinks the pedal is down and it wont turn on.

 

thanks for the tips. I'll look into them.

 

does anyones cc work in here i have yet to see a thirdgen with a working one.

 

both my 91s, and my older 82s worked.

heck, i had the verts cruise working even when i swapped it to carb for a bit...

 

PhAnToMs, I don't know if that was a rhetorical question, but mine works fine.

 

My 88 Firebird's CC worked when I got the car and then misteriously stopped a couple years later... I figured it just died, til a little while later the car started running like crap... found out it had a vacuum leak. Replaced the hose, and the cruise worked perfect again.

My 89 GTA the cruise works too... once in a while it acts up and won't work... my guess is dirty contacts in the switch maybe... but majority of the time it works.

 

Wow, with just those few words you really opened up a can of worms, lol.

 

Yeah, I learned a dirty trick you can play on your friends w/ firebirds. In the engine compartment on the back wall above the the steering column there's a box with a vacuum line running to it. Disconnect that hose and the car will still run but extremely rough. I found that my 82 T/A was running really rough, the engine was sucking in air from somewhere. We finally found that that vacuum hose had disconnected from the plug and was sucking in air. Although! I strongly discourage using this trick on the innocent... or anyone who carries a firearm in their trunk. Messing with a person'spontiac is scrilege and blasphemy.

 

heres one for the later ODBII cars.

go over and loosen their gas cap.

since its not pressurized anymore, it'll set off a code and the SES light comes on.

hours of fun.

 

What is the box from which you are disconnecting the hose called? I am trying to figure out if that has something to do with my HVAC and Cruise Control failing simultaneously...

Thanks!

That box wouldn't apply to your car, it was only on the earlier models.

 

my cruise control cable doesnt fit under my open element air cleaner.. never got around to making it work
