I have a 2002 jeep liberty sport and the heater is only blowing warm air. I just put a new radiator in about 3 months ago. The heat was blowing out really good last year. I just want to know if anyone has any suggestions, cause its getting cold out... BURRRRRR!!!

Might want to repost the question in the general section - get more views

however the 2 things I can think of
1) on the radiator replacement - if there was an air bubble and it didn't refill all the way - low fluid - won't circulate through the heater core.
2) the Thermostat may have died open - keeping you cold

and FYI - the temp gauges - are 'indicator' only - they're computer readouts and they're non-linear - some dashes might be 30-40 degrees between spaces and some are 1-2 degrees.
