No I haven't checked the pump. I will do so. I suspect the switch, though because of the loose feel it has when I move it to the wash position. Feels like there is a loss of spring tension or something like that. It appears that I will have to remove the steering wheel, (with the air bag, careful) to access it. Is that right?
Check power at pump first , then , if needed , replace switch. -----------1)REMOVE UPPER AND LOWER STEERING COLUMN COVERS. 2)TURN STEERING WHEEL TO RIGHT TO ACCESS TO SCREWS IN COMBO SWITCH AND REMOVE THEM. 3)DISCONNECT CONNECTORS. 4) WITH A SMALL POCKET SCREWDRIVER RELEASE PLASTIC RETAINER TAB ON MAIN BOX OF SWITCH AND PULL SWITCH OUT.(IF YOU CAN'T SEE THE 'CLIP' USE A LIGHT AND LOOK WHILE WIGGLING THE SWITCH ...YOU'LL SEE WHAT I'M TALKING ABOUT.) GOOD LUCK.---------------Do I need to say 'installation is reverse of removal...I hope not.!..Have fun.
