check the vaccum hoses on the passenger side under hood. I think that there are two hoses but it might be three. they get brittle and leak. but they move a little valve that you can move yourself just to see if heat works then. it is inline with the heater hoses I think. Bear with me though because it has been about 3-4 years ago when I figured this one out. it is definately a vaccum problem. there is also a set of vaccum hoses under passenger side of dash, several colors in it. might want to look there because sometimes kicked by peoples feet but money is on the ones inline with heater core. just move linkage and see if it gets hot air. Hope I helped and didnt confuse.

U should have the accuracy of the gauge tested before u spend any more money on this, factory gauges are not very accurate. U are still in the normal zone though no matter what the other expert says, and jeep Cherokee's run hotter than 195 due to how small the engine bay is, my friend and fellow tech works for a jeep dealer and says hot running on V6's and overheating esp on the V8's is a common issue even on new trucks.

Look for a loose connection to the temperature sender unit on the motor.
If all connections OK, you may need a new temp sender unit.

1-Place a large drain pan beneath the radiator drain plug. The drain plug is located on the passenger side at the very bottom of the radiator on the engine side.
3-Loosen the drain plug. On the 2000 Blazer, the drain plug is a wing-nut type of plug. Twist it with your fingers until the coolant begins to drain.
