Question about GMC Yukon
It seems strange that all this happened at once, there are 4 different power circuits, i think the first thing to check would be the central plug in for the right front door, you will find the plug in behind and just above the right kick panel, remove the panel and check to see if the plug has came apart, also their is a right door circuit breaker that powers up the right door control module it is located in the instrument panel fuse box it is a 25amp circuit breaker ( the box is located on the left side of the dash between the steering column and the left kick panel ), you cant look at them to see if they are working so just remove it and install a 30amp spade fuse in it place if every thing works with the fuse in it place then replace the circuit breaker with a new one.
let me know how it comes out.

Could be due to loss of connection to the window door panel. This can be due to wire break in the harness to the front door panel.
You will need to remove the panels of the two front doors and check individually with a multimeter the power to the panel printed circuit board. Check on the + 12 that is the + B to the circuit. Now depress the switches and check the contacts. If there is absence of the negative ground to the circuit. If so loop a +12 to the circuit to confirm.
All the circuits cannot fails unless with a common cause and if the fuse is intact then this can be the possible reason unless if there are errors/damage in the panel board.

Check your radiator fluid level, if it is low it is a good chance your heater core or the hose to the heater core has a leak. The heater core is a small version of a radiator which has the air from the blower blow across it to force warm air into the cabin of the vehicle. You will need to probe under the passenger's dash to locate the leak.
