18 Colorado BCM problem?

2018 Colorado, the air conditioner clutch won’t kick in, after disconnecting battery it works for a while and then stops. How can I diagnose the BCM?
What scan or diagnostic tool will help on this? Can’t justify 5 grand for a really fancy one, but I would like something that will help
Thanks

Welcome to the forum, there are many scanners that can access bcm info, just do an online search, not crazy expensive.

Re: 18 Colorado BCM problem?

That looks like a decent scanner for the price.

If it works a while after you reset by disconnecting the battery, I'm wondering if maybe it's somehow heat related. FWIW
