During this time of year, heat into the passenger compartment is greatly needed. I found open windings on the auxiliary heat pump motor even though the voltage input was good at 12vdc. Can this pump be bypassed without risk to the heater core? Absolutely. The pump is quite restrictive when it is not running so I would recommend you remove it from the circuit. I used a high temperature plastic 90 elbow plastic fitting of the type you find in the hardware store for plumbing hot water in houses. I try to avoid copper as dissimilar metals can result in electrolyses, and the copper may migrate A seized aux hot water pump has been known to draw enough current to burn out the climate control amplifier so if it is bad, get it out of the circuit Regards, Jim Friesen Phoenix AZ 79 300SD, 261 K miles 98 ML 320, 138 K miles
