Yes, and I don't remember. I think Art knows.

From FSM here is the location description: I have not looked for it..
Behind Right hand side of I/P-near the rear of I/P compartment.
If that means interior passenger compartment under seat is my guess, but why do i get the feeling it is in the trunk?
Anyways on the pin listings I don see cruise light or anything like that mentioned under the BCM. Closest mention is the multifunction chime control.
Here is the cruise schematic if that helps...If I get a second in between my long shifts, I will dig further & see what I can find on the dash cruise light. I get the feeling it can be programmed on as a test ....with a tech 2 scanner.

I am not sure about your model year PA, but on mine it was in behind the glove box.

It should look something like this.

Jmrosen'* PA has a 2002. 1997-2005 was the new redesign PA. The FSM info & schematic above is from a 97 PA.
I was shocked when I first removed the rear seat to find the front accessory fuses were under the rear seat...The BCM may be there as well, cant remember ...

Circuit 817 of your schematic Art. If you notice, its only a single wire. Which means this wire is a data wire. It carries multiple signals such as what gear the trans is in, the status of cruise etc etc.

Yes, I have a 2002 PA Ultra. original owner, the car is in absolute pristine condition. I'm meticulous with preventative maintainence and I fix anything that is not working immediately. This issue has me so frustrated. Is there any reason to replace the brake peddle switches too? All the brake lights are working as is the cruise, it'* just the light on the dash that doesn't work. The tech 2 was limited in diagnosing. It did get the green cruise light to turn on with the same kind of test as the bulb check when turning the key to auxiliary position. The green cruise light does illuminate then, It just does not work when the cruise is on when driving. Again, I've replaced cruise modul and ECM. With guidance here, I'm hoping that BCM will indeed fix this. What else could this possibly be?

if it does work on light test, it has to be a programing deal with one of the modules or cluster. i dont think i would go through all that hassle for that though, programming is going to get expensive. most car didnt even have a light until recently

My family were Buick dealers and I'm friendly with the local Buick GM dealer where I live. I'm getting a break on the labor so it'* not too bad. I want this fixed. There was no programming for the cruise module and the programming for the ECM took 20 minutes. Can't imagine the BCMs programming would take very long. Is there anything you can think of that would cause this IF it'* not the BCM once I have that done?

its just an educated guess based on knowing how the car works. i would have to have access to diagrams and the gm service manual for your car to be 100 percent sure. i have neither. they should have both at the buick dealer and should have been able to say one way or the other what the problem is

I'm still trying to get this resolved. I have now replaced the cruise control module, the ECM and now both brake light switches. Still no cruise control light? Is Possible For the multi function switch to be working and engaging the cruise control but not the light? Is there a lead on the harness to the cruise control module that is just for the cruise control light on the cluster? Also if the bulb test is showing the light working isn't it unlikely it'* the cluster? My tech and I just can't seem to figure this out. I've gone this far and I'm determined to resolve this. Any help would be greatly appreciated.
