I acquired a beater 1980 3/4T Chevy, and pulled the evaporator housing to re-seal at the firewall. I cannot find a drain provision for the condensate. My 70' Chevelle has a drain at the bottom of it's evaporator case. That is a TXV/POA system. This 80' is a fixed orfice system, and I'm puzzled about the condensate issue. Currently the ac is non-functional, so visual observation is not possible. What am I missing, that the GM engineers knew? Thanks
Opps, after a detailed closer look, ... there is a drain hole in the case, by the firewall. I'd been looking for an obvious molded drain, like my Chevelle.
