HVAC problem

[djbmw]

Antone ever had a problem with the "climate contol".
My haeting and air conditionong work fine but the fan will blow fast or slow "on it's own" The little graph will change when you press the fan speed button but the fan ranadonmly goes fast or slow no matter what the speed "says"
Any idea the problem or solution

Search for final stage resistor. This is one of the more current symptoms before it fails all together and then, it will blow fast all the time.

It not to hard to change, because I even did it :D
