1996 Oldsmobile Bravada Water Bzck up

yes there is a hose that goes throught he floor on the passenger side by the front of the transmission on the passenger side. just take a piece o f stiff wire and twirl it around inside the hose to get eht water out. you won't hurt anything and you'll probably get wet.

Thanks for the tip about the water back up in the a/c & heater housing. Now I think the heater core is leaking because I found antifreeze on the driveway this am. How big a job is it to replace the heater core ?? Still do not see any liquid on or behind the floor mat. Thanks Fred

you have to pull the dash out of the way to get to the heater core. It's ap retty big job as it will taek you probably all day to do and you have tobe careful doing it.
