Your smell of antifreeze could be a heater core starting to leak or the heater hoses are leaking at the connection at the firewall.get it up to running temp and be careful and see if the hoses feel the same temp .Also it could be a bad radiator cap.all these things can be test with a coolant pressure testor that you can borrow at auto zone store .I dont recommend many of there major parts like alt.starters,brakes but the do have several tools to use.plus there are 2 recalls on that model that are still open campaigns 1 is the shifter detent the other which is most important is the front brake rotors are defective it is call crystalized metal if you hit the brakes to hard they will explode and no stopping or if one brakes it can through you one direction.I just check this recall lastweek because one of my friends wantedd to go a few more miles on his pads well he was on the hiway traffic slowed quick and he hit the brakes he went under the corner of a semi and lets put it this way from the neck down was ok.The vehicle is in storage and I examind the jeep for court and I ran the vin and never were changed.Just call a chrysler dealer and ask for a vehicle check to see if there are any open campaigns on recalls have your registration with you to read it off the vin numbers it is 17 combo of letters and numbers

Are you saying there is no air coming out of the vents, or the air is not hot ??
If both heater hoses are hot and the air coming out the vents is not, you could have a blend door problem under the dash.
The blend doors direct air thru the heater core and the vents.

    Yes it could be the blower motor or a blend door problem. You should be able to turn the fan on high and feel it coming out the vents. Someone would need to pull the blower motor out and check it.

SOURCE: heating system blows only cold air

it maybe a blend door problem. if both hoses at the firewall for the heater are close in temperature its not likely a heater core. the actuator for the blend door is located on the bottom of the heater/ac box towards the middle of the bottom. it will be a tight fit but you can remove it without removing any part of the dash. take it off and disconnect the power. start the vehicle and manually move the door and see if the temp changes

Yes you do need a heater core, if not replaced it will only get worse.

OK. So the blower notor isn't operating. Do you have power to the blower motor? The resistor is new from what I got. If you don't have power to the blower motor, then check the speed control switch and fuses. If you have power at the blower motor, replace the blower motor

Unplug the fan on sensor. It should have one green wire and one black wire. Use a paper clip and jump the two wires. Turn the key to the run position, the engine does not need to be running. Does the fan come on? If not check the green wire for 12 volts and the black wire for ground. If there is no ground than run a new ground wire. If the is no power check the heater/air conditioning fuse in the under dash fuse block. If there is power and ground make sure both the cooling fan fuses are good and both the cooling fan relays are good.

2002 deville has not hot or cold heat


I own a DeVille. Check your large hoses to see if they are warm when the caddi is warmed up. Do you have blowing air from your fan? If not, check the fuses and swap relays under the hood with each other to see if it a relay. You may have a bad blower motor, but check the relays and fuses first. If all those check out good, replace thermostat for warm heating. This will not effect the cold heating. Last and very important. Are you losing antifreeze? If you are, you may have a blown head gasket. 4.1Ltr engines are known for this seeing that most people do not change their antifreeze often enough. Good luck. email me at tvandenhoy@hotmail with your diagnostic results.

Overheating


IT COULD BE THE FAN FUSE OR FAN RELAY, IF THE FAN IS DRIVEN BY THE ENGINE TRY CHECKING THE FAN CLUTCH. IF THE FAN SPINS FREELY WHILE IT IS COOL, THEN WAIT FOR THE ENGINE TO HEAT UP AND SHUT THE ENGINE OFF AND TRY TURNING THE FAN BY HAND. IF THERE IS LITTLE OR NO RESISTANCE THEN REPLACE THE FAN CLUTCH. IF THE FAN IS ELECTRIC THEN REPLACE THE FUSE AND RELAY LOCATED UNDER THE HOOD IN THE FUSE PANEL. HOPE THIS HELPS. PLEASE KEEP ME POSTED. THANKS FOR AN HONEST RATING AND FOR USING FIX-YA. BEST OF LUCK.
