Turn Signal Switch Problems of GMC Canyon

Bought our pristine 2007 GMC Canyon sle in Nov 2017 with 45, 471 original miles. Been very happy with it until lighting quirks started about a year ago. The last year or so the turn signal and brake lights have pulses where they decide to not work correctly. Then work fine for months, before acting up again. We actually had our Canyon in at the GMC dealer in Dec 2019 for loos intake manifold repair, 2nd time in last 9 months. . The service manager told us we also had no brake lights. I said I did not know that and I was now concerned how long they have not been working, and that we have had intermittent turn signal issues a number of times in the last year. Comes and goes. I then asked if there was any brake light or light switch recall on our Canyon. I said I remember seeing a recall notice on consumer reports. He said their is no recall on our Canyon. They said they fixed the brake light with a new brake pedal brake light switch. Tonight the lights started acting up again. When push brake peddle, left turn signal turns on. Left turn signal was also intermittent function, occasionally this last week. Tonight it had a hard time figuring out how to work, flash correctly. Then, while driving home tonight and with my kids following me in their SUV, when we got home they said the Canyon needs to stay parked until repaired. They said my turn signals and brakes light are totally messed up and not working. No left running light, no left brake light, and right brake light on full brightness the whole time. They could not tell when I was braking or using the turn signals. Interesting how the dealer service manager did not recommend to us that they replace the light switch anyways, just to be safe.
