SOURCE: 1999 Lincoln Navigator Heating Problem

if the heater core is getting hot then the problem is the air temp control blend door actuator, a common problem.

2006 Lincoln Navigator. I have replaced driver side blend door actuator. I am getting power to it. Tried the 9 volt battery. Not getting heat to driver side.


Probably the DCCV has quit working. (DUAL CLIMATE CONTROL VALVE). Might be located near radiator? Splits out the heat to the heater cores. don-ohio

Radiator fans randomly shut off


  • Relays carry high-amperage current controlled by a low-current switch
  • When a faulty relay is not replaced, the circuit will either be non-functional or remain engaged. here's your relay you need.

HOW DO I FIND WHICH RELAY IS FOR THE HEATED SEATS


I'm not finding a relay that controls the heated seats (this doesn't mean there isn't one), but I did find a Climate control seat module which is under each seat. There may be a "multi-function" relay that controls the seat and other things, most likely located under the hood in a black box containing other relays and fuses, the lid should have a diagram that tells you what each one controls.

Heater blowing cold air antifreez full 1999 lincoln navigator


is there a thermostat for the heater loop the same as for the radiator loop on your car cooling system.

1 some cars have thermostats to keep the water just round the engine when the engine is cold and then they open as the engine gets warm to get the water cooled it seems that the water is not coming to the heating circuit so there maybe a thermostat valve that is stuck in the closed position and needs replacement
2 alterativly the heat control lever mechanism is stuck in the cold position and needs to be freed up or the control valve replaced.
3if the system is electrically controlled with no manual levers for heat control then a fuse may have blown or some other electical problem in the heat control mechanism.

Heat works in the rear but not in the front,the blower works but it blows cold air


damper in duct to change air flow from heat to air is not working most probably. I am almost certain the navigator will have an actuator motor that has stripped, or the motor has gone bad this is constantly working when you use climate control to control air temperature.

2006 Lincoln Navigator. My driver side heated seat is flaking out. I turn it on after starting the vehicle and it comes on for about 20 seconds and then shuts off. If i push the button a second time it...


Electronics involved !
The climate control seat system is able to heat and cool the front seats. Each climate controlled seat is operated by push-buttons on the dual automatic temperature controller (EATC) located on the instrument panel. Each front seat temperature is then monitored and controlled by the dual climate control seat module (dual CCSM) located underneath the passenger front seat cushion.

Both the driver and front passenger climate controlled seats are independently controlled electronically by the dual climate controlled seat module (CCSM) mounted to the bottom of the passenger seat cushion. The climate controlled seat system only operates with the engine running, however, if using a diagnostic tool to command the dual CCSM, diagnostic testing can be carried out with the ignition switch key ON engine OFF (KOEO). The system receives power from central junction box (CJB) fuse 118 (30A) through circuit 1153 (RD/BK) feeding battery voltage into dual CCSM C3265b pins 1 and 24. If power is disconnected from either pin 1 or 24 of dual CCSM C3265b, only 1 seat will be disabled (pin 1 for driver seat, pin 24 for passenger seat), the other will remain operational. Since both climate controlled seats operate independently, if a fault occurs setting a DTC specific to either climate controlled seat, only the affected seat will be disabled by the module and the other will remain operational.

Sorry , but it would be best for you to take it to the dealer or someother qualified repair shop.
