91 Chevy Sub 1500, 5.7, 700r4/4L60, 3:42 gears, 4X4. I thought at first that I couldn't open the door because of all the freezing rain that we have been having but things got warm enough to melt everything and I still can't open the door. I have tried both the inside and outside door handles as well as cycling the door locks both by the electrical door lock switch and manually with no luck. There is also a rattle in the door so I imagine that part of the hardware has slipped off its correct location. I know that given enough time I can get the inside door panel off but it really seems to me that the door has to be open to get the door panel off. Any suggestions for opening the door? Is it possible to take the door panel off with the door shut? Running out of ideas here other than the dreaded give up and take it to a mechanic.
