thermocouple is bad.
Check the control module, the resistor, etc......

If the heater fan works on all speeds, then the blower motor, blower fuse, blower relay, and blower motor resistor pack are all good. If the fan runs but nothing comes out of the vents, you have a 'mode door' issue (which might include a bad control head).
The blower motor is shot, if it doesnt come out of the vents, feet, windshield, anywhere, its the blower motor, take it in and get it fixed before winter comes, your heated leather seats wont keep you warm enough bud.
Yes. Hot water comes from the water heater. The blower motor propels warm air around the house through the duct-work, but is not connected to the hot water heater in any way.
If you have no heat in your 02 grand Cherokee limited blower works heater lines are hot good circulation just no heat comes out?Maybe blocked heater core. Also check thermostat.Your problem is with the blend doors in the GC. Check the HeaterTreater eBay listings for diagnostic information and a fix.
Does it work on number 4 though? As mine does the same thing. And is due to the blower or something that needs looking at. Number 4 comes straight from the engine which is why it will work.
under the hood, passenger side, on the blower motor housing, towards the bottom, under the motor bump out.. unplug the wire clip from it, it comes out with 2 screws.
Check the blend door motor/mechanics or heater control head
This is caused by a broken heater matrix. I have had this problem and its is a real pain to fix as you need to take most of you dashboard off to get to it.
First of all, check the fuse on the fuse box under blower motor. If the fuse is ok, the blower control switch could be the culprit. nius: ford contours are known for their fault heater blowers, the switch melts as well as the connections to it... the switch is 20 bux, for has a recal on the plug (10 year 100,000 mile which ever comes first) take it to a for dealer and they should fix it for free
