    Blower speed

    When I use AC on automatic function the blower speed has recently become erratic. What do y'all think? TIA

    Belt or exhaust drive? Does engine RPM or exhaust tone also change? What happens when AC switches off? First guess: PCM is not adapting or attempts to but is off the map.

    It's the HVAC blower. What's involved in investigating and replacing BCM?

    Problem(s) solved. BCM replaced; right front window stopped, window regulator replaced; intake manifold gasket replaced. Tech said module was a little rough but he did not have to remove any hoses. Parts $202, labor $315. I already had the gasket. Great customer service. The guy's a wizard!
