NO year Wangler makes this hard..... no year, no joy. sorry/

engine at 180F and holding, that is step 1
step 2 is, the blower fan runs on high, at full speed
yes/no?
and last , if the heater core is hot (feel it)
then the dampers are wrong.
on my 08 i feel the 2 hoses on the core as they pass through
the fire wall, are they roasting hot (180F)
then if air passes through the core,said air must get hot.
if you feel nothing at vents, in all modes, the main TEMP. damper
is stuck closed, (this is the red and blue knobs)

the 10steps that work on any car, they all have a heat exchanger.

I do I test/troubleshoot a heating issue for a vehicle?


Also, besides coolant level, the heater core may be restricted and the temp blend door may be inoperative .

Dan how do I bleed 2004 Kia coolant car temp is good but sometime at idle heater starts to blow cool hit throttle gets great heat


I agree with your logic. Attached vid addresses bleeding. Sounds like at low rpms, not enough flow to transfer the heat. So bubble or maybe a partially obstructed core. There are a couple of vids on clearing a core... GOod luck, let us know if you figure it out.

My ford aspire heater not heating up


Possible thermostat. It is responsible for letting the vehicle reach operating temp is a short time period. If it is stuck open it will take forever for the heater core to heat up.

Second possibility is that you might have a plugged heater core. Let the vehicle run for 10 min then feel the two coolant hoses that go to the firewall on from the engine compartment. They should be relatively the same temp as the upper radiator hose. If the temp is way different from one hose to the next (heater hoses that is) then you have a heater core problem

Okay where my little data screen shows the temp, etc. said check tmp system. What does that mean?


If your reffering to the vehicles screen then i would first check the coolant level. It might just be low and it is letting you know. If that is not the case then check what the vehicles temp is running at when your driving. It may be telling you the vehicle is over heating.

1993 dodge dakota 4X4, 185.000miles LX Model 3.9 , runs great had since feb 1993. Problem, very little heat, thermostat has been changed, coolant is good. Takes a very long time to obtain any heat and...


If the vehicle reaches operating temp ( where you normally have good heat ), and the heat is still slack I would suspect your heater core is partially blocked and a backflush would be the place to start. If your vehicle isn't reaching operating temps possibly a thermostat failure, or overcooling issue ( this is why you will see cars / trucks partially blocking radiator flow by means of a cover that's snapped on or some other means)

2003 Ford Ranger Heat Sensor


if you are referring to the coolant temp sensor and not the coolant temp switch,then yes,this sensor tells the ecm what temp the engine is at and the ecm delivers the correct amount of fuel to the vehicle.The switch in most cases just sends the signal to the guage or light.

Car temp gauge/heat


TDIs can take a while to heat up in cold weather. Sometime 10 minutes or more.

If it is taking longer than 10 mins for your temp gauge to hit 190, you may need a new temp sensor, which is pretty cheap and just pops into the engine block, almost right next to the battery.
