check the drain under the battery
check the pollen filter housing as they leak
also check the air con drain tube
lift the carpet and check the cdl ecu in black box in passenger floor
remove the accelerator pedal and check for water ingress

[mark78]

battery drains are clear pollen filter sealed where will i find air cond. drain tube had carpet lifted dried out as best i could

[towcestervag]

the air con drain is located in n/s footwell
if you look at the bottom of the heater at front left corner just to the side of transmission tunnel it is a black plastic tube type object
