It wont start
The heat will also work when the car is turned on, but not moving. It uses heat from the engine.
get a new one
it will make you crazy
they have to be recycled and they wont work.
how sad :(
Must be an electrical short.
no but your defrost wont work well
if the serpentine belt breaks or comes off etc. the car will over heat as the water pump wont work. also it will die eventually as the alternator wont be working, as well as no power stearing etc etc.
A heat engine that uses heat to do work
Ogerize it.
