Weird problem with my cruise and it's not related to the brake switch like everyone else online I tested the brake and clutch switch and regardless the switch nonfunctional would throw a light on the dash when I do a cruise test. When I perform the cruise test by pressing the button sequence. I get no flashes and so to make sure it wasn't the switches in the steering wheel being faulty I unhooked the bpps and then got 2 or 3 flashes depending on which brake switch I pull. Now, as I say it's intermittent so sometimes it just works and has no issue and goes along perfectly fine, I did replace the cruise unit with one from a newer 05-07 model year I didn't check what year the car was in the junkyard, but I had this issue with the old cruise unit too. I'm not entirely sure what to check next I was thinking clock spring but the horn, buttons, and (hopefully) airbag works. the SRS module can communicate with it but not immediately after a battery removal (don't know if that's relevant). All the brake lights work I even got a spare center light that I tested and it still has the issue. all my rear lights are normal bulbs not LEDs (except the OEM center light). I can provide more info if needed
