Hi, was thinking this was a pretty dead site.
So, I'm organizing a casual meet up in Garden Grove (Main Street Car Show) this summer with several other Bronco owners.... More than welcome to swing by...
Its just a bad motor... a bit of pain to get it out. I replaced mine a few years ago. Though, if you hear the motor running... its the plastic gears that are broken. You can gear kits on ebay. Either way has to come out.
