I had trouble with my cancel cam recently. The Doorman part did not work for me so I found an AC Delco part number that was much better. I did a quick compassion in a thread i did recently. The AC Delco part is 26047013. Got it on Amazon, was twice what the Doorman cost but was much better quality. Might help, might not.... Good luck.
