More 보다 likely, the warm is comes from the heater core, which way that girlfriend probably have actually a bad actuator. This link is because that the LeSabre, but the systems are very similar & it gives some an excellent info on attributes & places of the actuators. Click below

Just want to make a point about the name of each of the actuators. Your car has 4 actuators:1 - fresh Air Inlet actuator (1) #9 in previous diagram - together the name means it opens the door that allows fresh wait to get in the air distribution system. Throughout winter and also summer the exterior air can impact the workload of the compressor and/or heater core. For instance, in the summer if the external air is 95 levels like the is below in central Florida right currently then the compressor will need to work harder to cool that air to say the 72 degrees you have it set to. If you were to use the recirc button then together the cabin air cools climate it would store cooling that air and also if the within gets under to 80 levels - 15 levels cooler - climate the compressor only has to cool down an additional 8 degrees instead of the original 23 levels from 95 to 72. 2 - blend door actuators (2) #52 in diagram for left side and also #23 because that the ideal side - there is a blend door actuator for each side of the cabin. Therefore the passenger deserve to choose one more temp for comfort. If the passenger regulate is not set different, resets after each engine restart, climate the 2 actuators work as one come cool the entire cabin.Just a fast note on the CJ2 device - the compressor constantly cools the wait coming off of the evaporator coil come 36 levels - the blend doors then rewarm the wait coming off of it come the preferred temp by bypassing the air through the heater coil. Once you first command the AC to max cool on a hot day the amount of reheating is minimal but, together the wait in the cabin to reduce closer and also closer to the set temp then much more and more warmer air is added back in. I seem come remember the there are additionally some ambient wait controls the might likewise limit just how much warm is offered based on very hot or very cold temps.3 - setting Actuator (1) #51 in diagram however can"t be ordered so you order #53 and also #51 comes through it - the mode actuator move the doors in the air distribution system that directs the air the end the countless vents - consisting of defroster, prior vents, bi-level (front vents and also heater vents) and also heater vents. I think that if you choose defroster you additionally get heater vent as well.The setting actuator deserve to either be regulated manually or through the automatic climate regulate system. If you select manual then any type of command entered on the control panel will make the actuator relocate to the preferred position. If you select automatic the system will continually change the position of the actuators to accomplish the temp that has be selected.Testing:1 - air inlet actuator - revolve the vent button on and see if you odor the exterior air and then revolve on recirc and see if that smell walk away. While it"s difficult to see the actual door relocating you have the right to remove the gloves box and look way up close to where the A column would be for the windshield and you can see the white equipment moving within of the actuator. That doesn"t necessarily median that the actuator or door isn"t damaged - just that the electrical signal got through and also the actuator tried to turn the door. I would certainly say the the opportunities of the air inlet actuator being broken are lower than for the mix doors. 2 - mode actuator - simply press the air Flow switch on the regulate panel and you will certainly feel the air transforming it"s output from one collection of vents come the next. If you perform then it"s not broken - if friend don"t climate either the actuator is broken, the door is stuck, or the electrical control system is not functioning properly.3 - mix Door Actuator (a.k.a. Temp Actuator) - these room harder to test due to the fact that the are constantly moving and even if you view white nylon equipment moving the doesn"t average it"s really working inside the actuator. Over there are many photos of the gear transforming the outside part but the outside component isn"t able to grab host of the door linkage and also turn it. And also if the outside part doesn"t work that way you need a whole new actuator. Some world have to be able to open up them up and also fix the nylon through some kind of epoxy but I"m not sure exactly how long the settle lasted in those cases.The great thing around the blend door actuators is that you can see castle much simpler than the wait inlet actuator by simply removing the driver and passenger hush panels you have the right to look up in the center of the instrument panel (IP) and also see lock moving. Through the method - every actuator has actually 255 discrete positions that the controller can have them collection to. On ours 1998 year version you can turn the key on with the engine off and also leave the that means for 5 mins and the actuators will go with a recalibration come make certain the 1 and also 255 positions space at the boundaries of motion for the actuator.You will have to do this reset if you execute wind increase replacing among the actuators.I think many of the actuators run about $75-100. IIRC the air inlet actuator and also the right or passenger blend door are actually the same part number. The left blend door is a different part number as is the setting actuator component number.If you carry out wind up needing the setting actuator you"ll need to order the bracket the it go on and also the actuator will come through it. It take it me a few days to track that down awhile ago when among the various other members here had trouble locating that part. If you look top top the link that HotZ28 sent out you"ll see all of the parts listed.If it to be me I would certainly look closely at the blend door ~ above the side where the warmth is coming out also much. Especially if the other side vents have an excellent temps.That"s a lot of of info so allow us recognize if you have any an ext questions.Good luck!
