Question about 1999 Jeep Wrangler
I wrote yesterday I had a new radiator and thermostat put in and am getting no heat althought it is blowing air-I appeciate the response on getting lines blown but guy said he did that and he also recommended a new water pump because fan blades may be rusted and not pushing hot water up to blower Could this be a problem?
Make 100% sure before you go and spend more $$$ that (1) you have good coolant flow through the heater core; get engine to operating temp,then with heater fan on high and temp control on full hot carefully grasp heater in and out hoses(i use a in-fared heat gun to diagnose). They should be very close to same temp, if not, core is plugged or if equipped with a flow control valve, its not opening or there is an air lock in system.(2) If coolant flow is good, suspect the hot/cold blend door being stuck in cold position assuming you have good air flow. Its very rare for engine cooling to be ok and heater core coolant flow be bad , caused by a failed water pump! Hope this helps! Please rate me,Thanks!
