Iam driving a JD 5075E. Up until yesterday when I would turn the blower motor on(Heat/AC) it wold work on all 3 speeds now it only works on high speed.Has anyone experienced this problem. Do you think its the blower motor or the switch? Thank ou

Generally speaking, if you can only get a high blower speeds, the resistors are toast. All speeds begin as "high", and then the current is diverted into resistors to lower the voltage and get lower speeds.
The resistors are generally in the ductwork somewhere so that the air flowing past them cools them. This is pretty "general" but I'd look around for something that looks like that. A parts manual page would probably get you on the right path. I've never operated any tractors but "open station". They use a non-electrical system to weld or freeze you anatomy to the seat.

Resistor module is out under the cab roof towards the rear
