Help unlock power doors on Suburban with no power

My 1992 Suburban has back doors that are electronic and have no key entry. Last night I drove to the hospital, visited for three hours, came out and completely dead car.
Put key in, short sound meaning key was in, then nothing.
I have a year old battery so we tried to jump the car. Nothing. There is nothing there and no power to unlock the doors. Could it possibly be a fuse?
The complication is this - I was recently hit by another driver and the front is bent. I have been able to drive the car with no apparent problems. Other driver's insurance has totaled the car. The suburban is loaded with merchandise and I must get the items out before they can pick up the car. There appears to be no power and I have to be able to open those doors to get things out. I can open front with key, but can't get access to the cargo area completely. Any suggestions or way to get the doors open? Obviously, I don't want to spend excess money and the car is still sitting at the hospital's parking lot.
 Need help as soon as possible!

There are fusible links that protect the circuitry from the power source (battery) going to the different systems. A fusible link is a short section of wire, two sizes of wire smaller in gage then the circuit wire that it’s protecting. On this truck you’ll find a main link at the battery which leads to a junction block on the right side of the firewall under the hood. This junction block will have a number of links that feed the different circuits. Anyone of which if burnt out could give you this problem.
After saying that, it (the problem) may have nothing to do with power feeds but could be a ground problem or something as simple as a loose connection somewhere close to the source.
Your best bet is and I know this isn’t what you want to hear; is to have someone that knows how the system is designed to work check it for you. It’ll be cheaper you having it towed to a repair facility then the hospital towing it to a compound.
