Tip & How-To about Vehicle Parts & Accessories
I've been researching Ford 2010 air conditioner failures, and have read on many threads the problem is a "Filter drier" problem that starts with the freon getting contaminated (with filter desiccant balls that remove moisture, bursting, and clogging up the whole system) and causing extreme pressure, cutting out the limit switch, which stops the compressor. Ford does not want to recall this problem. Simple fix? NOT
#1 Check the high low pressure of the freon... (Some have suggested a release of freon from high side of the system helps temporarily)
#2 Removal of the freon, changing the filter drier, and a recharge of freon, will fix the problem (filtering most of the contaminates) in most cases providing all the fuses were checked out "OK"... Fan relays etc..
Thread from another Ford owner.......When I turned on the AC for the first time this year it made a loud grinding noise for a few seconds, then never cooled.Took it in to the dealership to check and for regular 45,000 mile maintenance.
Dealer called and gave the following description of the problem ..."in the AC dryer there is a filter bag with "little blue balls" of desiccant. It seems that it is a very common problem that these filter bags burst and flood the entire AC system with the balls (aka "debris") which causes all the parts to fail and or clog. Many of the parts can't be effectively flushed so the have to be replaced." The cost to replace the entire AC system (all valves, tubes, hoses, evaporator, compressor, condenser, accumulator, dryer, etc.) came to $2,022.65. This dryer unit that is causing all the problems is a non-serviceable unit and is in no way affected by regular maintenance, and there is nothing that can be done to prevent a failure.
The cost of this part alone at national parts stores (Advance/Autozone, etc.) is around $30.00. This very inexpensive part however causes extensive damage to very expensive parts. I would call this a "manufacturers defect". Also the replacement dryer used in the $2,022.65 repair is identical to the one that failed.
