Thanks daveb, sorry for the delay, I had missed your reply, and then had left my SMB for three weeks up in WA. Back now and am trying to identify what system is in place. Here is a photo of the condenser in the back. There is no auxiliary compressor, so it is just a 12v system. Are there any other ways to distinguish between Starcool and Danhard?
Prior to it failing, I would operate the system by having the stock A/C on at the dash, engine running, and then twist the knob above the driver side to Lo, Med, or High. Even now, when the A/C is turned on at the dash, refrigerant does go to the condenser in the back and the coils are cold. I just can't get the blower back there to come on. I also can't find a fuse anywhere that might control that blower fan.
Secondary question: I also suspect the Ford dealership will have underfilled the refrigerant, going with just the stock amount. I have seen other posts that the Starcool III requires 4.5 lbs, but wondering if my system that lacks the 110v compressor, would require less than that?
