Kevindjac Posted October 23, 2021 Share Posted October 23, 2021 I am currently experiencing an issue with the cruise Control, I have looked everywhere for a vacuum leak to no avail, I'm thinking it's the servo, but haven't had time to test it yet also cruise still works see the click the link to see pic! https://linksharing.samsungcloud.com/kHtLPtAPtX2a Link to comment Share on other sites More sharing options...
DAVES89 Posted October 23, 2021 Share Posted October 23, 2021 That's interesting. I have never dealt with a warning but yet have it work... Link to comment Share on other sites More sharing options...
Padgett Posted October 24, 2021 Share Posted October 24, 2021 Agree unless the battery was disconnected in the middle. Link to comment Share on other sites More sharing options...
Ronnie Posted October 24, 2021 Share Posted October 24, 2021 I would check to see if there are any BCM codes stored in diagnostics that might give a clue to what is going on. 1 Link to comment Share on other sites More sharing options...
Padgett Posted October 24, 2021 Share Posted October 24, 2021 B448 is a good one. 1 1 Link to comment Share on other sites More sharing options...

I agree code B448 is a good one in the fact that it can usually be easily be corrected by adding Freon. I have no idea what it would have to do with the cruise control not working. Unless you can explain the reason you posted that all it amounts to is a distraction to solving the problem at hand which is a cruise control problem.

Padgett Posted October 24, 2021 Share Posted October 24, 2021 Is very simple: brane fade. Shouldabin B552 BCM memory reset (usually happens when change battery). Remind me not to post from memory. 1 2 Link to comment Share on other sites More sharing options...

Kevindjac Posted October 25, 2021 Topic Author Share Posted October 25, 2021 (edited) Thanks for the codes guys I'll check it out on my Wednesday when I'm off, incidentally the heater core is shot also, residue on passenger side window above defrost vent, then the cruise Control issue started coming up shortly after that not sure why but anyhow thanks I'll keep ya posted.

Kevindjac Posted October 27, 2021 Topic Author Share Posted October 27, 2021 (edited) So after much digging I found out the brake switch can affect operation of the cruise Control. I checked the it, it was pretty far out of the bracket under the dash, I pushed it back in and the input showed high on the diagnostics and lo when I pressed the brake pedal so hopefully this will fix the issue. I love this forum and the AA forum so much info at your fingertips, thanks again to everyone that has gave me advice.

Kevindjac Posted November 7, 2021 Topic Author Share Posted November 7, 2021 So the brake switch pushed into the bracket didn't fix the problem, so I'm off the next few weeks after my wife has her surgery Tuesday I'm going to go in deeper into it and remove the servo, it had no continuity but I'm going o try again maybe I didn't have ohm meter set right, wish me luck have a great day and I'll keep ya posted! 1 Link to comment Share on other sites More sharing options...
Kevindjac Posted November 15, 2021 Topic Author Share Posted November 15, 2021 So this is what my servo looks like on the inside, it doesn't look like any wires are broken on the coils but yet I get resistance reading on the prongs. https://linksharing.samsungcloud.com/iMkr4PHcNXVS https://linksharing.samsungcloud.com/xfQfGzHwWooi If anyone sees anything but dirty coils, that I'm not seeing let me know. Otherwise the only other thing I know is to replace it that being said anyone know where I can get on for a decent price? I found one on O'Reilly's for $90+ tax.

DAVES89 Posted November 16, 2021 Share Posted November 16, 2021 Most any junk yards [I go to You Picks] has them for way less. The servo is on millions of G M cars. Link to comment Share on other sites More sharing options...
Reatta 89 Posted November 18, 2021 Share Posted November 18, 2021 I don’t know if you fixed your problem yet but I had a problem with my cruise the light would come like it was working but it didn’t do anything changed the headlight switch and problem solved.

I'm impressed with your troubleshooting abilities. How did you arrive at the decision to change the headlight switch to fix a cruise control problem?

DAVES89 Posted November 18, 2021 Share Posted November 18, 2021 I ran into that when I was swapping switches from the Red car your dad got from me into the Red I currently have. The cruise would work intermittently and I was swapping cruise servos thinking that was the problem. That wasn't it so I remembered that I had swapped the switch and shortly after that the cruise issue started. So I swapped in a different one and the cruise worked as should. So the lesson learned is that sometimes even if the indicator light is on that doesn't mean the switch isn't bad. I also do not touch any buttons on the headlight switch other then the headlight off/on switches. I leave the cruise switch engaged and the fog lights are set in the on position and are never touched. Link to comment Share on other sites More sharing options...

Without hearing about the experiences you guys had with the headlight switch being the the reason the cruise wouldn't work I would never have thought about it being a potential source of the problem. I learn something new about these cars everyday. I also leave the cruise and fog light buttons engaged all the time so maybe that is the reason I've never had this problem. 1 Link to comment Share on other sites More sharing options...
