Then it was fine for 2 days till driving on a fairly flat road with cruise on at around 55mph on a very slight incline it downshifted to like 4th and wound up then upshifted, did it a 2nd time about 1 min later and I canceled the cruise. About 1hr later it was doing the same thing multiple times.

From buying research to owner support, join 1. Hey guys my ac recently started acting up on my silverado.. Auto ac.. Doesn't cool as it should. Got the ac system vacuumed and recharged and didnt change anything. Seems like the ac is a lil cooler when the fan is on low and not as cool on a higher setting. I got code b Also think the passenger side vents may be throwing a lil colder air than the diver side Looked up the code and i found it might be a faulty drivers air temp actuator. What do you all think , should I replace? Anyone know where its located? Read up that these have 4 actuators..

Hmmm, b0413 gmc, just one more thing I have to keep my eye on. I get in and my stereo is still on but no display. Under-and-over pressure safety switches.

Low reference, 5V reference, position signal, and 2 control circuits enable the actuator to operate. The control circuits use either a ground or 12 V value to coordinate the actuator movement. When the actuator is at rest, both control circuits have a value of 12 V. In order to move the actuator, the HVAC control module grounds one of the control circuits while providing the other with 12 V. The HVAC control module reverses the polarity of the control circuits to move the actuator in the opposite direction. When the actuator shaft rotates, the potentiometer's sliding contact changes the door position signal between V. When the module sets a commanded, or targeted, value, one of the control circuits is grounded, and the other is supplied 12 V.

Came out, started driving and noticed the heater was blowing "cold" air, even though the setting was on 90? The passenger side was blowing hot air at the normal 90 temp. I stopped, turned the Acadia off, started again, no go

They said passenger side temp valve actuator shorted internally - from the invoice - 'diagnosed DTC B' estimate to repair, I verified that the actuator was indeed not moving, then ordered and replaced actuator with PN
