The AC condensation drains out at the bottom of the passenger fender
The evaporator drain is at the bottom of the evaporator on the passenger inner fender under the hood
Not the best location as it cause rust at the bottom of that fender to develop
The evaporator was moved in newer year Cadillacs more to the middle back of the engine bay
It appears that it just drains around the evaporator inlet pipe around the bottom of the evaporator housing? Wonder if it would work to carefully a hole in the housing and install a drain tube down?
