An updated kit can also be purchased from jeep and will require the complete removal of the dash and HVAC unit.

SOURCE: I have antifreeze leaking from under jeep but

Not knowing how many miles you have on your Jeep, this may or may not be the case; check the water pump. If the shaft seals fail, there is a small hole on the bottom edge that allows coolant to flow out instead of it causing more serious problems. It may not be easy to determine this since belts and fans tend to scatter it all over.

If your interior floor isn't wet, the heater core is probably OK but if you have air in the cooling system, it will affect the cabin heating.

SOURCE: 1992 Jeep Wrangler heater not blowing hot air

How often has the coolant been changed? My only guess is that it hasn't and the hoses and the heater core are plugged up with goo and a flush is needed

SOURCE: PASSENGER SIDE HEAT NOT WORKING

The passenger blend door is broken on its shaft into the air cooling assembly.
The disgnostic is very easy, the part itself is very cheap. The bad new is that the dash has to be removed to reach the HCAV assembly where the blending doors are mounted. 15 hours labour time to replace it by an experienced technician. There is a kind of bypass solution developped and 'marketted' by a company. I have not install this fix by myself so far. Up to you to check if it could be interesting for you.

Coolant leaks heavily from passengers side. Started yesterday morning on the way to work. I noticed the vents weren't blowing hot air. Then I noticed the car start to overheat. I didn't drive any more...


Ok, may i suggest that you check your HEATER COIL, you can located it by pulling up " HEATER COIL" for your specific vehicle, this is what your coolant travels thru while hot and air passes thru this coil to produce the heat to warm your vehicle and typically the heater coils are located on the passenger side. Now as far as the leak location, check heater coil connections it could be the coil itself. GOOD LUCK!

How to replace thermostat on


Do this when cool. Take radiator cap off, start the engine, turn on heat (not defrost) and now top up coolant to about an inch or 2 from top of radiator, as level drops down, and let vehicle run until the radiator fan comes on, then off, about 3 times, and add coolant as needed while it's running. After that, put radiator cap back on tight & make sure return bottle is filled to proper level. Now try that & see how heat is, temperature gauge etc, and keep an eye on return bottle level for a while. Let me know how it is.

Heat works on driver side, passenger side blows cold air.


Did you check your coolant level or was it low and you added to it at some point? If so the system my need to be bleed or worst case the thermostat is going bad.

Blowing Cold Air


Sounds like a heater core. Check the passenger side floor board. Sometimes when these go out there will be some water on the passenger side floor. Hope this helps some.
