Heater Blowing Warm Air
It's already getting cold in New York State and I noticed my heater was blowing only warm air...any ideas to get it on the hot side as it should be?

I haven't done anything with my jeep for heating, but on my 94 Bonneville I had only warm air coming out it was due to a bad heater core and blower.
Check the floor boards for rad fluid and under/around the dash.
Just my 2 cents

Eric331gt you hit the nail on the head...local mechanic also suggested I flush the heater core so I disconnected both heater core hoses at the front of the motor and ran a garden hose in the top heater core hose for about 15 minutes then ran it in the bottom hose for 15 minutes... reconnected the 2 hoses to the motor and now the air from the vents is HOT.....thanks to all for your comments. NOTE: Just used some duct tape to hold the garden hose to the heater core hose. Obviously leaked some but did the job.
