The windshield motor needs to be replaced on my 1996 Mercury Grand Marquis.

I purchased a Haynes Repair Manual, went to page12-11 and followed the instructions.

Everything went well, until I got to the part that told me to.....#5. Unplug the electrical connector and lift the wiper motor from the housing.

The motor has a plate attached to it that would not come out of the opening into the housing.

What is the correct proceedure to take the windshield motor out of the housing? I do not want to tear into the housing and take it apart until I know if this is the correct way to proceed.

Thanks!
