My new 98 E300D has had the leads to the auxiliary water pump cut. I can only surmise that the reason that this was done was that a failed aux water pump was adversely affecting the climate control system (yes, this can happen, don't let anyone tell you otherwise), the connector was stuck, so they simply cut the wires. So, I'm trying to decide whether to replace the pump (part is about $200 new) which would also involve installing a new connector to the leads.

The only ill effect of leaving as is is weak vent heat at idle. And of course I have other cars to drive if I need piping hot heat at idle.

What would you do?
