Heater blower motor either does not work or works weaker than what speed is set, until I make a right turn. When in a right turn the blower speed appears to increase to the actual setting speed. Once the wheel straightens out, the speed returns to either no blowing or less than speed set. Vehicle has to be moving. If parked, and I turn the wheel right, nothing changes. Turning left makes no difference.

Yep, this happens when the blower motor itself is going out; here is the location of the unit so you can change it out, which should fix the problem. I am sorry but it looks like the dash will need to be removed to access the blower motor which I have included instructions for. Just take your time and you can do the job. Check out the images (below). Please let us know what happens. Start by disconnecting the battery.
