how do you fit a heated rear window switch in a bmw 316i compact auto 95. It is situated to the right of the heater control knob.

Take out the fuse to this circuit so will you not get a shock or damage the circuit. Disconnect from back and remove, then put in new one. However, if you have a BMW you should be able to afford a mechanic to do a proper job. working under the dash is a pain.
