Re: fan selector and a few random q's
Alot of car's have a resister that allows changing it. I don't have any idea with that specific problem. But I'd try swappng a new selector (as they are cheap from a jy) and then look at the blower motor.
I had an 01 sunfire that had the same problem, and there was a resistor on the blower motor that was the problem.
As for the tranny swap. It's a bit more difficult. First off, do you have cruise? On an auto, the cruse shutoff button is set to the break, it's the clutch in an auto. Also, you have to rig up the deal to allow you to start out of park (netural safety switch, I think).
Plus the tranny has to be from the same generation. Either 88-91 or 92-94. While it is possible to swap across gen's, it's a bit more of a pain. The mounts were slightly different along with afew other things. One guy swapped a 5 speed from an 89 into his 94, and had to make afew trips to the yard for oddball things to get the 89 tranny to work properly in the 94.
