2002 Dodge Ram 1500 heater problems

Hi, I am wondering if anyone has any information about a heater problem with a 2002 Dodge Ram?

I have a 2002 Dodge Ram 1500 with a 4.7 engine and my heater does not work at all. Has anyone else experience this issue or know what I could look at to figure out how to fix?

Please let me know.
Thank you in advance for any help you can offer.

May be a Air pocket in the engine

Have you got your problem fixed. If so I would like to know what you did to fix it. I have the same problem with my 2002 dodge with 4.7 engine. It is fine around town and short trips but on long trips it will start overheating after about an hour of highway driving. The heater blows cool air all the time. I changed the Water pump and thrmostat. Switch the heater hoses. A mechanic told me he thought it had a steam pocket in the engine. If you add coolant and don't get air in the system it can cause a air pocket in the engine and turns into a steam pocket not allowing water to circulate. On top of the engine you will see a bleed screw that you should open when fililng with coolant until it flows out of it then screw it back in. I did that and it still doesn't work. I read where you can drill a 1/8 hole thru the side fo the thermostat and it lets air pass by but I have not tried that yet.

I have the exact same problem on my 2002 ram

Have you gotten anywhere with your overheating problem? I have the same problem and am not sure what to try next. I just chaned my thermostat and the heater is working great but it is now overheating worse. I wonder if the thermostat I put in was bad.

Justdoit,

Tell us what you have done besides thermostat. Have you done a coolant flush?
