© DenLorsTools.com Summary: Recent comments from a do it yourself-er that has used a previous article on Jeep Grand Cherokee dash removal. Jim was nice enough to let us know how he has used our information not just once, but on two occasions for different problems. The ability to tackle dash removal has saved him a ton of money. I think we saved Jim a lot of time – now he’s returned the favor by basically writing this blog! Thanks Jim.

© DenLorsTools.com Summary: Jeep Grand Cherokee’s with dual zone have a common problem of blend doors breaking at the point of actuator engagement. Vehicles affected are 1999, 2000, 2001, 2002, 2003 and 2004 Jeep Grand Cherokees. The automatic temperature control can be affected on the driver or passenger side, making the temp control inoperable. Until recently the refrigerant had to be discharged and the dash removed for repair. Now with a WJ blend door repair kit # K6855685AB, from Mopar/Chrysler/Fiat the repair can be done in the vehicle by even modestly experienced individuals. The kit includes an aluminum door door, a plastic door, a spindle, grease and patch material for resealing the evaporator case after repair. PDF Jeep instructions provided in this car repair article.

NOTE – Since this article was written Jeep has discontinued this repair. We used to sell an alternative however, we have discontinued that item also. See HeaterTreater.net for a possible solution.

© DenLorsTools.com Summary: This article is about Dodge Ram pick up trucks that have a common air-flow problem with the HVAC (Heating Ventilation & Air Conditioning) system. The problem causes little heat (or AC depending the time of the year) to flow through the vents. The blower fan can typically be heard with no abnormal sounds, although no air seems to be making it out of  the vents. We go over parts that need to be removed to gain access to replace a common failed component.

The Robinair AC Machine is one of the most popular units for car air conditioning service.

©DenLorsTools.com Summary: In this auto repair article we discuss the reasons why a car’s air conditioning system may leak water inside the vehicle. Sometimes the fix is simple and other times the repair can be much more labor intensive. As an automotive technician that’s worked over 25 years in Florida, I’ve dealt with this problem many times on different models. If leaks aren’t fixed quickly, the carpet and padding underneath can become a breeding ground for mildew and harmful bacteria. People with certain allergies can be affected the most.

Pictures are of a 2004 Dodge Stratus like the Chrysler Sebring – click on images for a larger view.

© DenLorsTools.com Summary: In this automotive repair blog, we provide some helpful information on how to R&R (Remove and Replace) the evaporator in a 2004 Dodge Stratus. Replacing the heater core is basically the same job, except for the replacement of the receiver drier. These tips are for the 4 door sedan, yes the the coupe and the convertible may be different depending on the year. If working on a different model or year it would be advisable to refer to an auto repair manual. Auto repair manuals provide detailed info on changing components like the evaporator in any model. Just keep in mind that for evaporator or heater core replacement, most of them will say “see removal of instrument panel.” Which is accurate except for the fact that if all you’re doing is moving the dash to access the evaporator case, dismantling the dash isn’t really needed. If the instrument panel is removed as described in most auto repair manuals, many more parts will be removed unnecessarily.

Leaves accumulated near the fresh air intake can enter the car’s evaporator case.

© DenLorsTools.com Summary: Article on low flow from air conditioning vents in cars. Neglected cabin air filters are the leading cause of this issue. Although, there are several things that can cause low airflow from a vehicle’s air conditioning system. The strongest blowing vents are the middle ones with the setting adjusted to maximum or recirculate. On the max setting, the air is recirculated in the passenger compartment. Obstructions can include leaves, loose articles from the glove-box, a broken or out of position door in the Heating Ventilating & Air Conditioning (HVAC) case.

Robinair AC Manifold gauge set was originally for R12, it has been adapted for 134A

To properly diagnose an AC system the use of a manifold gauge set is needed. AC gauge pressure readings help professional auto technicians determine if the system is low and exactly what is going on with the car’s A/C system. A 134A gauge set is also used when attaching a vacuum pump to the car for evacuating/removing the air out of AC components. If air is left in the system, the moisture it contains combines with refrigerant under pressure can cause a corrosive acid to form that can destroy evaporators, condensers or even the AC compressor from the inside.

Get your A/C checked at a local shop or check it yourself? Freon will need to be added by someone.

Summary ©DenLorsTools.com: Adding Freon or topping off a cars A/C system is the most common task performed to restore performance and get cold air blowing again. However, adding refrigerant isn’t always the solution for car air conditioning problems and troubleshooting may be required before just charging a car AC system.

© DenLorsTools.com Summary: Common cause of 2002-2005 (Third Generation) Ford Explorer and Mercury Mountaineer low airflow issues covered. Broken recirculate doors can affect airflow from the blower fan if the main air inlet door has fallen.

The fresh air door is also called a recirculate door, max air door or main air inlet door.
