Rear screen blower
 

Good day folks, I have a problem with my 94 325i convertible rear defrost. It doesnt work when I push the de-frost switch. The light comes on when the switch is depressed and I've checked the fuses and even hooked up a new blower but no joy. The previous owner had a hard top and I was wondering if there is a connector or something to re connect before I start chasing wires. Any suggestions would be appreciated.
