Customer Question

I have a 1998 Chevy 1500 Express Conversion Van. The rear heater has a drip leak behind the rear tire on the driver’s side. I want to bypass the rear heater but there are 3 lines going up into the heater. Is there a way to know which lines to bypass without accessing the rear heater to see where the lines go?

One is likely for the a/c. Can you attach a picture of the 3 lines, then I can direct you which ones to bypass.
