93 Cherokee Sport 4.0 liter
While I am driving down the road my heater works great. However, when I stop for a long stoplight or at a drive-thru, my heater starts blowing cold air. When I start driving again, the heat soon returns.
Could this be linked to my overheating problem? It seems that everytime my temp guage goes over the 210 mark is when my heater stops working.
My Jeep has had a recurring overheating problem ever since I bought it. When I stop moving for more than a minute, my temp guage goes up to around 220. If I let it sit for 30 minutes, it will eventually reach just below redline, but never beyond that point. When it overheats, I do not hear any boiling and the Jeep runs just fine. I assume the problem is simply the guage, but I could be wrong.
I have replaced many things trying to solve the overheating issue including multiple radiator and engine flushes, many new thermostats, new water pump, new heater control valve, and new hoses. My Jeep is showing no signs of a blown head gasket and I have took it into several mechanics trying to fix the overheating problem, with no luck.

I have searched the forum several times trying to find a similar problem but have been unsuccessful.
