OK, my blower resistor went out last Sunday, had blower speeds on 3rd and highest speeds, but no AC compressor operation. On speeds 1 and 2, AC compressor kicked on but no blower motor.
So I fixed that today. First, I cleaned out the glove box. The little wooden divider I made stays installed. Note the accessory 12 V receptacle where I keep my cell phone plugged in.
Glove box comes out. Remember which way the latch points before you unscrew the two screws holding it. Keep the door retainers on their correct sides when you unscrew those. For mine, I also removed the two push-on connectors to that receptacle. View from rear, showing that receptacle.
View after removing glove box, note the relays and switches for the AC.
The blower resistor is more to the "outside" and more difficult to see, its coils are hidden inside the air box assembly. See this from the manual. The screws do face straight down, as shown. There are two wire harness connectors to it.
It removes by unscrewing two Phillips head screws, then removing the two harnesses. Well, I said two harnesses, but mine had one harness, one block-off, and a thicker blue wire.
Note the broken middle coil on mine.
Note that mine contained a "harness to nowhere" to block off the "C" terminal, there's only the "C" terminal in that smaller harness.
Of course, all four of my parts yard spares were different than mine, and didn't have that wire.
Using Electronics 101, I saw that wire also went to the "C" terminal on the blower resistor, so I cut the wire off my broken one, and crimped on a female push-on connector and attached that to the "C" terminal in place of that "harness to nowhere".
Then I buttoned it all up, and it works again. It was Mrs. Cusser's birthday, and we took the bikes on the B2200 bike rack (in the 2-inch receiver hitch) and did about a 15 mile bike ride on the park bike paths, from mid-Scottsdale down to the Tempe Lake north of Sun Devil stadium. Then I took her to lunch at Scottsdale Restaurant she chose; with tip: $47, but I was able to get a Four Peaks Kiltlifter Scottish ale, extremely good).
