I pulled a box trailer weighing under 3500 pounds for about 15 miles. once I parked shut off the truck and unloaded everything I went to start up the truck, the shifter was stuck in park and wouldn't light up on the dash so I had to pull off the plastic tab to shift. the check engine light is on. airbag light is on. a/c wont work it blows air but not a/c.
any ideas on what it could be? blown fuses?
