Good evening.

It sounds like the blower resistor is defective. That is what controls the blower speeds.

1. Disconnect the electrical connector from the blower motor resistor.

2. Remove the blower motor resistor screws from the HVAC module.

Was on freeway going sixty five mph car just powered off. Once stopped I waited about half an hour since it was 104° outside. Tried and would not start so I had it towed. Next day checked my fuses and the fuse for fuel pump was blown. But forgot to mention my AC light kept blinking off and on. Not sure if that had anything to do with it.

I changed the fuse and started back up. I drove it again trying to put AC on but this time just blew hot air and about ten minutes later my car powered off again on the freeway. Check the fuses and fuel pump fuse was blown again.

It sounds like you may have a failed or shorted fuel pump. You will need to have it checked to confirm. It may be seizing up when it gets hot.

I would start there and have it checked.

As far as the AC, you will need to start by checking to see if there is any Freon in the system by doing a pressure test.
