Dealership Cheating Me Out of Cruise Control
I recently installed cruise control on my girlfriend's 2008 Cobalt LT, but to my disappointment I have not been able to activate it in the BCM. I spent several weeks researching the installation before I spent any money. Then I bought a leather SS steering wheel from a 2009 Pontiac G5. My girlfriend preferred her original vinyl wheel, so I changed the wiring harness and the bezels.
On the positive side, I didn't have to custom-wire anything. The BCM wire for cruise control was already present in pin 61, and the wiring from the stereo head unit to the clockspring was already intact, so the steering wheel audio buttons worked instantly.
The cruise control button lights up, but I knew that I would have to take it to a dealership to have it activated with a Tech2 and Candi module. When I got to the dealership, I told them what I wanted, and then I waited 20-30 minutes while they "attempted" to program it. When they failed, I provided the following printed instructions:
If your dealer or garage doesn’t know how to configure the BCM for cruise control, print these instructions for them:
1. Using their tech2, build the car.
2. Select Vehicle Control Systems, then navigate to Computer/Integrating Systems.
3. Once in the Computer/Integrating Systems menu select Module Replacement/Setup and follow the instructions on the scan tool.
4. It will ask a bunch of questions regarding the options on the car, one of them will be about the cruise control, just say yes it does have this option.
5. Finish set-up and you're done......takes about 5mins
After I gave them the instructions, they drove the car back behind the magic curtain and returned about 5 minutes later. The mechanic came back with a "how dare you question my intelligence" attitude, and told me that the Computer/Integrating Systems option (Step 2) is NOT an option with the LT. He highlighted the SS on the URL the page was printed from, and said that you have to have an SS for this option to work. I argued that the wiring exists for cruise control and that the buttons light up, so in theory the car should accept it. His response was that Chevy simply uses the same harness for everything, regardless of which options a car has or does not have. "We can't just grab stuff off the internet and make it work."
The mechanic said the only avenue he is aware of would be to contact Chevy directly to have a custom program written for programming my BCM for cruise. He said that a VCI number would be assigned to this program, and that he could load this VCI number to run the program. I have never heard of this before. Any thoughts?
The dealership still charged me $55, even though they didn't activate the cruise. I KNOW that this can be done, because I have read about people successfully doing this for 2007-2010 Cobalts on this site and other similar sites on the internet. So in my mind, there are three possibilities:
1) The mechanic is incompetent and too proud to admit that he might not know everything. He probably didn't even reconnect the Tech2 and immediately disregarded my instructions without even trying.
2) The dealership knows that this can be done, but because they are crooked, they lied to me.
3) The Tech2 has been changed so that my 2008 era instructions are no longer valid. The only reason I can think of for this would be another way for Chevy to eliminate DIY options for cruise control.
Does anyone have any insight into my situation? I'm very discouraged, but I'm determined to make this work. Thanks in advance! Any advice will be very much appreciated.
