Blwer works on 1 and 4. But will burn the resister on 2 and 3. Also will blow heat but then just stops and how's straight to cold an vise versa when air is on

Hello, this sounds like 2 separate concerns. The blower speed controller or resistor continuing to fail for some reason could be as a result of some kind of electrical concern with wiring or circuit protection. The temperature control issues sounds like it could be heat from the engine or a temperature blend issue. All of this is way too wide open to offer you good advice in this forum. Testing will be needed to determine the source of the concerns.
