Temp Question

If the heat gets too cool thru the vents you may need to put a higher rated thermostat in it to brung the temperture up some as mopar to ya said new cars have electric fans so they kick on and off our oldies have direct fans that run all the time so with the cool weather its still cooling evan more.A 180 thermostat will be alot cooler air thru the vents than a 190.
