Finally got the air exchanger out of the K1500. Now to work it over, clean it, lube all the hinges, and replace the heater core. Yep, it was an obvious leaker. Found where it was leaking no problem. Looks like something may have made it's way into the vent box and poked a hole in one of outer core tubes. Looks to be easily repaired but I'd imagine it's pretty dirty anyway.
