No heat
Ok so I have no heat in my 2001 grand cherokee Laredo 4.0l with a 42re trans. I have check the thermostat, working good opening and closing. Check the I let and outlet lines for the heater core, all are hot with good flow. Check the fluid level and condition. Again all is well.
I'm thinking that the blend doors are stuck, I don't have dual zone climate. It's vacuum operated.
Any idea???
Thank you
It's bloody cold.

It may be inlet door problem. I may be wrong, but I think your doors are electrically moved.
