Cleaning the Dodge and Ford evaporator cores can be done much easier than removing the dash. Removing the blower motor and the blower motor resistor will allow you to use a flexible air powered liquid applicator that pulls some liquid cleaner from a container. I use commercial A/C evaporator cleaner for aluminum cores. A short piece of vacuum tubing or fuel line can be added to the end of the applicator tip, thus allowing for a better covering of the evaporator core face. Soak the core and let it sit for a few minutes. Then using a water supply with a flexible end, wash down the core face. Having a small flexible exam camera makes inspection of work much easier. May be necessary to repeat this several times as the dirt and dust can be stubborn. Protect the floorboard area with plastic bags as some water may overflow if you use too much pressure. Check drain to make sure it stays open during this time. Duct tape over the resistor hole may be necessary. Soaking the resistor is not a good thing.
A secondary way is after careful inspection of location of evaporator core, CAREFULLY drill a 3/4" hole inspection hole on the blower side of evaporator, taking care not to drill any lower than 3" from the bottom. Taking a LISLE radiator cleaning wand which sprays a 90 degree pattern from the tip, insert into casework allowing the water from the tip to clean the core. Core cleaner can first be applied thru the access hole before water is used. Plug the access hose with a plastic plug of proper size (buy plug before drilling access hole). You then have permanent access hole to clean core.
By using these methods, in 40 years I have very seldom had to pull a core to clean unless it was plugged with animal hair or very small grass seeds embedded deep within the core. Deep fungal growth in the core is also a another impossible job requiring replacement.Last edited by Airtech; 07-05-2016, 06:24 PM.

My 2005 F150 didn't have a cabin filter either. I guess I was lucky. As for online resources, I always order a subscription for each of my vehicles on www.AllDataDIY.com, and the Eric the Car Guy channel on YouTube is excellent.
