Climatronic or manual?
If it's manual, high speed does not go through the resistor. So, high
speed should work all the time even when the resistor low speeds are
Actually, it's the "thermal fuse" on the resistor pack that blows, causing
the low speeds to not function.
If it's climatronic, it's either the climatronic control module or the
control module for the fresh air blower (controls ground for
motor according to signal from climatronic).
