Cedrick Cyle Engine Reviews
Do you think my thermostat is stuck closed on my 99 Jeep Cherokee?
The temperature Gauge rises to 210 degrees and I'll have heat radiator fan when he does not floor.Electric on.When I select defrost the radiator fan turns on and off never stays off.Engine Temp at 210 degrees, but the heat in the cabin rotates cold.Selecting position further statement will not bring back heat and fan always not cyle on and off
210 on the gauge is normal (distance may be a Little, the standard thermostat for this car is a 195 deg). If the gauge reaches 210 and still, all is Well there. When you select defrost, air conditioning system comes in. The cold defrost and the air heat to defrost the windshield. The condenser Cooling fan will always operate in this mode. You or a blend door or defective Motor or a bad Controller. If it is a Grand Cherokee with automatic temperature control, it has a capacity of integrated diagnostic it is in the computer. If a Cherokee plain jane, I suspect blend door motor.
