'95 Sport 90 A/C Woes

[Kneale Brownson]

I don't know about changes from differing models, but I've removed the 
evaporator from my '87 5Ktq driver and its '86 parts supply because of 
nonfunctional A/C  and  need to extract newer heater blower motor from the 
latter for installation into the former, and there's not much to taking out 
the evaporators.  After extraction of gases (probably, as in my case, not 
necessary if you've already lost them through leaks), there's two  hose 
disconnections, some snap-apart wiring disconnections, a drain to take 
apart and four screws to remove.  I don't know about parts costs, but labor 
shouldn't be anything like $800 unless the 90's have a completely different 
arrangement.
