I'm sorry to hear about your dad. Glad to learn of another Pantera in the area that I didn't previously know about. The Pantera Club of Northern California (PCNC Chapter of POCA) meets this Thursday at Coco's in Sunnyvale.http://www.panteraclubnorcal.com/events/monthly_meeting.htm
One of our members who comes regularly also lives in the Danville area. Contact me off list and I'll send you his contact info. Maybe the two of you can come to this week's meeting together.
There's nothing to be intimidated about when it comes to working on a Pantera. Turning wrenches on a Pantera is like turning wrences on a vintage Mustang, albiet some things are just a little more difficult to reach. We have excellent vendor support and club support, and this BB as well as the DeTomaso Mail List are excellent resources where everyone willingly shares tips, tricks and experience.
PCNC also holds regular tech sessions where we gather at a club members house and wrench on our cars together. It's great to have a bunch of folks who are experienced at wrenching on a Pantera present when you attempt a fix/upgrade yourself for the first time.
Regarding your window does the motor make noise, but the glass doesn't move? If so, it's most likely your window gear - the factory gears were plastic and get brittle and break over the years. All the vendors carry brass replacement gears that will last the life of the car. If there is no window motor noise, your switch may be shot. This is also common. See this link for inexpensive replacement switcheshttp://pantera.infopop.cc/eve/forums/a/tpc/f/9350045562...960064844#5960064844
If you need a replacement switch, be sure to order 2 since the Bosche replacement switches are not an exact match to the original. You will want to replace them together.
Anyway, I look forward to meeting you soon.
