I can turn my heat on and it runs fine but when I turn my defrost on it makes my truck shut off.
When driving or just sitting still and having to use the defrost on my trailblazer it makes
my truck shut off but I can run the heat and it won't shut off the truck. Please help.
That is a weird one try turning on the AC see if it shuts the car off. The only thing that comes on when you put your car on defrost is the AC compressor, if it's locked up inside it might stop the engine but I'm thinking you would hear the belt squealing like mad first.???
