1994 Buick Park Avenue Q&A
1994 Buick Park Avenue Question: My cruise control will kick off when I try to set it.
I was also having a similar or identical issue with my cruse control. Recently I took time to read what it says in the original owners manual (which I found on line) for my GM car (I own a 1994 Pontiac Firebird with a 3.4 V6, same motor, different bore). My car probably has the exact same or close to the same CC unit as your GM car. I discovered by reading my manual that I was actually operating my CC improperly. I should also say that operating it improperly used to work for me but stopped working a couple years ago. The method I was using (which stopped working) was to just turn the CC on by sliding the OFF ON R/A slider switch all the way over to the right. Then releasing it when I reached the desired speed. Mine wont operate that way anymore but... I tried the method laid out in my manual and it works perfectly. Here's how GM says to operate it...1) When you're ready to use the cruise control..move the "OFF ON R/A" slider switch on your turn signal lever to the "On" position. 2) Then, use your gas pedal (not the Off ON R/A slider) to achieve your desired cruising speed. 3) Then push the "SET" BUTTON the the extreme TIP (or END) of your turn signal lever for 1 second and release it. 4) Take your foot off of the gas pedal. That should make the CC work. If this is unclear, read what it says/ look at the diagrams at this link below on pages 72-75. I discovered much more cool and helpful information about my cruise control system by reading the entire section. For example...did you know you can reduce your set cruising speed by 1.5MPH increments, without resetting your cruise control, just by pushing that "SET" button again for 1 second and releasing it....? I always thought the only way to set a CC to a SLOWER speed was to turn it off and reset it altogether. I hope this helps. I have bad feet and know how important is can be to have a working cruise control. I use mine at every possible opportunity. http://shbox.com/pdf/1994firebird.pdf If it still doesn't work I'd look for vacuum leaks in the PCV system. Make sure the PCV Valve's fin is pushed all the way so it's snapped into the grove in the PCV Valve Grommet. There's also the option of getting your codes read/engine scanned but I know it's not all that easy for 1994 GM cars because it was a transition year for GM on board diagnostics systems. - firebirdbob
my cruise controll will shut off while I am goimng down the road and not turn back on until I restart the car. - cubear
