    Default 90 suburban ac box drain

    Hey guys my trusty 4x4 suburban has started leaking water out of the seams of the heater box, I know its the drain line clogged but a fairly thorough search has not turned up the hose. I thought I would post here before I started taking the old girl apart any help on locating would be appreciated!

    Here is a link to a thread with some good info: http://www.gmtruckclub.com/forum/sho...t=heater+drain

    On my 93 the drain is located beneath the windshield washer reservoir on the passenger side.
