The stalling could be result of faulty crankshaft position sensors. There were several updates to the sensors over this era, there could possibly be some trouble codes that indicate a possible fault of that nature. Do you know how to check for codes in your vehicle, it has an onboard feature that you can access.

The blower problem could be result of a faulty blower. If you could verify that power and ground are present when the blower is not working, then you need a blower.
