On the highway, it was taken back to shop via roll back. The tire was changed but when I went to leave there was no headlights, turn signals, radio, wipers the power windows would not work and no dome light. The car runs and the inertia switch was checked and was not tripped. I checked the fuses and they appear to be good. What would cause this and how do I fix the problem.

Take it back to the shop that broke something when they did whatever they did and tell them you're contacting the BBB, State Bureau of Automotive Repair Standards, and anyone else you can think of. They broke something while working on your car if everything worked properly before you took it there.

I've got to ask, why did a simple flat tire require it to be taken to a shop on a flatbed? Why couldn't it have been changed on the road?

My wife and grandson were in the car in a dangerous location. They got a ride home before the towing company arrived that is why it was not changed on the highway. The towing company used a rollback because the keys were not in the car. They did not do any work to the car and said they did not touch anything. It is very strange that this happened while in their care. I have spoken to the owner who claims all they did was pick it up and drop it off. Nothing else.
I need to know what an be done to fix it
Thanks for your reply.

There's a master fuse box under the hood. Check those. The cover should be labeled saying what each fuse/relay covers. Use a meter to check the fuses, don't rely on just looking at them. See if power is getting to those fuses.

The inertia switch is only supposed to cut off power to the ignition and fuel pump in case of a rollover accident.
