Question about 2002 Jeep Liberty

A few Problems: Starting, Heater & Radio

OK...so my Jeep Liberty has a few problems that I hope someone might have some insight into. Problem #1 - On really cold days it won't start. We have replaced the battery and alternator but still won't start on some really cold New England mornings. We have to get a boost and rev the engin 2000rpm's for a couple of minutes. Problem #2 problem is that on really cold days the heater does't heat up the car. The engine is running at normal temp but it only blows lukewarm air while driving on highway but on mild days I have to shut off the heat. Problem #3 is that the radio shuts off after running for 20 minutes and now it won't work all together. The radio still functions because on the really really cold morning that we get a boost the radio comes back on for 20 minutes and then starts blinking on and off until it finally quits working altogether. Can anyone help??

    I have a 2002 Liberty and have similar problems. #1 - I have needed the battery jumped twice within last 2-3 months. Battery was replaced a week ago with no issues so far. However my mechanic and place where battery was purchased did not think it needed replacing... #2 - I do not have heating issues #3 Response given to problem 3 does not help in my situation..Radio will shut off after 45-60 minutes during morning commute. It did start-up during evening commute but shut off after 30+ minutes...Now it does not come on at all and the LED clock does not display. It did come back on when vehicle was jumped and after battery replaced.
    It appears radio is draining battery somehow... I brought it to a Dealership right after 2nd jump so the radio happened to be working and they couldn't fix something that was working... I got home 10 minutes after leaving and radio stopped working...
    Dealership & other mechanic said fuses either work or they don't.

Problem 1: buy a system heater to keep the engine warm at night.
You can buy them at any autoparts store . You take your pick from the variety.
Place a light 100 Watt Bulb near the battery but not too close to anything else where it might burn anything.

Problem 2. Check your coolant level to see if you have the proper level. Make sure you have 1/2 antifreeze and 1/2 water if you add any coolant /antifreeze and bleed the colant system. By running the car let it cool, then turn the radiator cap or turn the bleed screw provided on some cars near the thermostat outlet. Then adding some more water and coolant etc.The tightening the cap or bleed screw. When radiator is full. Check the radiator and and remove any debris that may be keeping the air out.

Problem 3. Will get fixed because your battery won't die.

I have a 2008 Jeep Liberty. The heater/air blower just quit working, I checked the fuse and that was good. What's the problem?


most likely its the blower motor unless it has a relay that you cant check you just have to replace it. sometimes you will have a few relays that are the same and you can use one just to see if thats the problem,but make sure its not one that controls anything major.

I’ve have problems with getting sufficient heat from my 2002 Jeep Liberty - Took the 2002 Jeep to dealership - First they wanted to replace the thermostat [$200], I explained it was replaced in November...


Here's the way I usually approach problems such as this. First I'll hook up a scan tool that allows me to see the actual engine coolant temperature is [not just what the gauge says] as the vehicle is being driven down the road at highway speeds. The coolant should be near the 192 - 200 degree range to get the best heat out of the heater. If the coolant temp is below that level then the amount of heat you'll get will drop according. IF the coolant is reaching full temp but the air coming from the heater isn't very warm then you could have a restricted heater core or a temp control door in the ductwork that isn't working properly and is allowing cold air to sneak past the heater core. Usually if you have a water pump impeller problem you'll also have an overheating problem as the pump often isn't able to move enough water through the radiator to keep the engine cool. Hope this gives you a starting point and good luck!
