On miy 99 the motor seems to leak during heavy rains. Any other day its fine. Is it a change out or do you think something is leaking on it.

the cover for the pollen filter is leaking, at the bottom of the windshield, you have to lift the hood. probably should replace the pollen filter while you're there.

I assume you mean leaking water. The blower is tucked up close to the cabin filters behind the dash. Air flow into those filters from right in front of the windshield. Its designed to only pass air but it can get clogged with leaves and gunk, allowing water into the filters and through the blower. It can also leak past the caps that hold the filter in place. Make sure the gutter underneath the cap is clear. I usually apply some Vaseline around the gasket with reinstalling the cabin filter to give a little better seal. They could use another set of hole at the mid section to screw it down tighter.

Just did a long search again and found the link that shows how to replace the filter. The filter on the truck is completely gone. Guess thats why the previous owner gave me a new filter from rover lol....thanks

There should also be drain holes or passages of some sort in the cabin air intake duct on the "dirty" side of the pollen filters. This is the duct leading from the outside cabin air intake between the hood and windshield that runs to the pollen filter on each side. My Rhino was clogged with wet leaves when I bought it because the thin screen covering on the cabin air intake had deteriorated. Water can certainly get in there and it needs to be able to drain out. I replaced all of the filters, shop-vac'd, cleaned everything I could reach and have not had a problem since. New pollen filter cover seals would not help if this is the problem.

Do you have any more info on this?
Mine too leaks water into the left hand footwell after heavy rain. Really don't think it is the pollen filter cover/seal - these are good.

The 2 pollun filters are soaked. I guess that can be the problem. Do I just put the soaked filters back in or leave them out and seal the covers. You can see the water dripping behind the dash. Only during heavy rain no car wash as such

This is the only description I could find in the service manual:

They call it a plenum. It runs from the pollen filters to the intake grill in the center of the car below and forward of the windshield wipers. I removed the filters and used a shop vac and various attachments to get the piles of wet leaves out of it to make sure it drains properly. You can easily test its draining ability by pouring water into the intake with a bucket or hose. I can't remember exactly where the drain holes are at the moment, but the intake plenum must be able to drain.
