I pulled the evaporator housing on my 90 to remove the right side cam cover. The housing is off, I did it without disconnecting the evaporator and discharging the a/c . I searched for a "how to tip" but didn't find anything useful nor was the SM very good. Is there any good write ups on this or any tips to reinstall? The two 7mm screws on the engine side bottom of the box was a huge tasks. Should I go ahead and discharge the a/c and pull the lines? What is the best way to tackle this as there is no "easy" way. Thanks. ( I know I need to make sure the seal to cowl is tight on reinstall). Hope everyone is staying safe and healthy.
