Here in the Phoenix area we hit triple-digit temps about 10 days ago. Son o'Gutz has been doing fine in the AC compartment for a couple of years now and I was just thinking about that when the cabin started warming up on my way home one day. Crap! Recharge time? So of course I went to open the windows, and nothing doing... sure enough, the windows are protected by the same fuse as the the AC. I recalled Art B's comment about passive-aggressive Swedish engineers...
After confirming that even fresh fuses would blow, I disconnected the line to the AC clutch, and the fuse still blew. After a couple more checks, it appears the relay itself is the problem; without the relay installed, the fuse won't blow. What's odd is that the relay coil terminals show open on the meter, which means they shouldn't draw current.
Anyone else run into an AC relay problem like this?
