May I ask is this a 2 or 4 door supreme? If it is 2 door and the handles are on the side beam you're facing a nightmare. Not impossible but a nightmare non the less. The rods in there are extremely weak. These locks, rods, mechanisms are intolerant of cold weather. Especially the internal bottom piece of the actual handle you pull. It's pot (cheap) metal and breaks under any type of duress. If ice was binding it, then it probably broke and is wedged in between the lock rods. I have a 93 conv and have been thru multiple nightmares with mine. I am on like the 6th drivers door handle since the car was bought in 1998. Ok first you are going to have to actually get that drivers door open which is going to require a slim jim and someone with some talent. I'd suggest a friendly locksmith. Once the door is open you have to take off the cover plate that covers the "rods". You will know if that handle is broken because the bottom piece will fall right out onto the floor. You have to go online and buy a new handle. DON'T make the mistake of going to the salvage yard to get one. You may find one there but it wouldn't be much fun to put it on and then have to do it again in ten pulls! In respect to the electrical issues, there are sensors in the door that if these rods are in a bind, will assume anything incorrectly. The problem should straighten out once the issues above are resolved. Hope some or all of what I put has helped.
