the two going for £87 keep the duel control, the one from heater treater uses only the motor on the glove box side
so both doors are held together with small grub srews on centre shaft.
just make sure the motors work before you pick one. you can just reach the back motor to feel the spindle to make sure
it moves when you work the temp control
Oh and try not to use a dremmel type cutter very messy. I drilled a hole at each corner and then cut it with a saw blade on a
swiss army knife. a lot cleaner and safer.
