Hi, Geoff in Seattle here!
I had a poor experience with Pierre Ford in Lake City
. When dealing with a pinched under-dash vacuum hose that caused the A/C to shut off when driving uphill, I was told all Ford vans are that way.
I had a good experience with the University Ford Service Center that used to be on Roosevelt in the U District (they took the time to properly find that A/C problem). Unfortunately this business is now gone.
I now take my Ford van to an independent mechanic -- Budd & Co. on Ranier Ave S
. They're pretty decent, and have dealt with several tricky problems in addition to regular maintenance.
