Interesting but I have a similar problem on my 1991 Acura The blower doesn't run and I think that it's frozen. I don't have power on the cigarette socket also. All the fuses look OK.
One day I started the car and a smell of pc board burning and smoke came inside of the car. The fan switch was in the middle position and didn't turn. I believe that a high current melted the contacts on that position. I forced the switch and it rotated. I started to follow the book instructions but I gave up after removing a few panels. Acceptability of the blower is not easy. I have the manual but doesn't help. I believe the manual isn't an accurate representation of the actual circuit. I am thinking of selling the car as is and let some one fix it.
The service manual was available on the Internet thanks to Tegger
