Maybe, on my '81 you had to solder in a new switch connector as the switch was soldered directly to the wires with no connector. Not sure of when they came with connectors. I believe that on the ones with the connector you just have to remove the trim around the switch to remove them > Second: the central locking system doesn't work.

What's leaking? if the pump isn't running at all remove it and apply voltage directly. try reverse polarity as well. If it runs you need to plug the outlet wqith you finger to make it switch over and then reverse polarity to run the other way. If the motor is ok then you have a vacuum leak. If that is the case, i.e. good pump, then report that back and I will go into detail of how to diagnose that. > Third: AC doesn't work which isn't too big of a worry yet. > repairable just > can easily run into a grand or more
