Riddle me this:

Ive got an issue with my drivers seat forward back switch? The up and down work fine, and and so i thought the motor was broken, swapped it with the passenger side only to find both motors worked fine so i reinstalled it. In order to adjust it i run a crude cable from the passenger switch to the motor which works fine.

This is where it completely buffuddles me . . !? If i put a voltmeter on the switch terminals and push button to move seat forward, it shows 12+ volts, as soon as I connect the motor to it, it drops to 0.40V?

As this is an MOT fail i need help solving this massive pain in my royal. Ive checked and swapped the drivers 30Amp fuse, didn’t work. What now?
