Not sure if your issue is the same as mine, but the motor that extends my generator out is seized up, I have to loosen a bolt and slide it out manually.
Does your model not have a door that uses a round key to open it on the front? Mine is right above the generator slide. Thru this door I can reach the generator breakers, and a few other critical things on the generator, and can also reach the windshield wiper motors, and several other key systems located under the front cap.
The bolt to release the generator slide is just under the front bumper area. I've not personally done it, but I've watched my mechanic do it a couple times.
I priced the motor once and it was around $250.
