This is my first post on here and hope someone can help out so My 17 year old Daughter dosent freeze in her 83 Turbo deisle

My Sister gave her the car. We had to drive from New york to Maine to get it and drive back home the same day
Everything else works perfect, Door locks, moon roof, you name it. Shes got 183000 miles on her
The car has the typical heat pump problem . Well maybe not so typical.
Its not getting power to the pump . I checked the fuses and all are good


I do know that iI need a new thermostat. Its running a bit cool

I think operating temp should be 80
When the cars in motion heat comes out but at idle it blows cool.
These are symptoms of a bad pump

Even though there power at the fuse theres no power at the plug. Is there a solenoid or secondary fuse?
