Question about 2009 Jeep Grand Cherokee
I know the last thing you want to do is take in in to the dealer but in this case its probably the best idea to get it repaired properly. If you insist on going it alone, you can always buy another HVAC control on eBay or somewhere like that and replace it. 50/50 chance it will fix it.

Fuse # 20, located in the Junction Block (interior, drivers side). This is a ten amp fuse.

SOURCE: Heater blows cold air
If the "Heater In Hose" gets hot, and the "Heater Out Hose" does not get hot, than either the Control Valve is sticking closed, or your heater core is plugged up with ****!
Have you used "Barrs Leak" or a simular product for a radiator leak? That will sometimes clog the heater core.
I have a 1993 Grand Cherokee, which "Normally" throws very hot air out of the heater, but lately sometimes it only throws warm air, till I make my first stop, than it gets hot.....all because the heat control valve is hanging up.
Low water in the radiator will also cause a heater to not work.....if the water level is too low to circulate to the heater.

you need a temp limited switch and for the most part its close to the blower motor has a small screw on each side with a plug in the middle give these websites a try www.autozone.com and www.alldatadiy.com if all fails stop by your Jeep dealership in the parts department and they be able to show you what i am talking about and print you off pictures and diagrams showing you where it is located wish you the best of luck Michigan Man.
