Yes ;
You are supposed to pry it's little white end cap off and lubricate it periodically , no one ever bothers (not even the Dealer) and they sometimes cause the dashboard to catch fire ! .
The good news is : this $135.00 part occasionally drops to sale price of under $50 and I've found some replacement ones on W-126's in the junkyards , of course you'll want to test it before buying a used one

Apparently if the Aux Water Pump is drawing too much current, it can whack the Pushbutton box. Anyone have any experience with this? They also mention the resistance of the monovalve and the blower relay amperage as two other potential culprits for whacking the Pushbutton box, but the warning for the Aux Water Pump is in red bold underlined as if it is really important.
