My 93 tracker has rust holes in the floor panel under the rear seats. Where can I get a replacement panel in Ireland? Can I install a new panel over the old panel after removing or treating the rust on the old panel for extra solidity? I've looked on the internet for a floor panel but they are very hard to locate.

For a 2000, it's more likely is that there's rust in the floor under the carpet. There are several drain plugs (approx. 30mm, actually filling manufacturing alignment holes) that often rust out. Fixing it requires that the seat be removed, the carpets lifted up and the rust cleaned / treated. New drain plugs can be made with some 20g steel sheet. They are usually pressed in, but can be glued with automotive gunk adhesive and sealed underside with stone guard spray. If there is real rust in the floor panel, cut out and reweld is required.

have you checked for holes in the floor. the shock towers rust on those. I had a 1995 that had rust in the truck floor next to the rear seat

This can be from one of couple sources. One would be a broken or missing rubber seal in the firewall. Water can and will enter the passenger compartment if the seal is not good or missing. The firewall is the metal between the engine compartment and passenger compartment. There are many penetrations in the firewall for throttle linkage, steering column, electrical harness, etc. All of these penetrations have seals to prevent water from entering. Check to make sure all penetrations have seals. Inspect from under hood and from under the car, too.

Another source is damage to the floor pan. If you went over a rock or jagged object without having enough clearance, it may have punctured or even sliced through the floor - under the carpeting and sound deadening material under it. If you live in a cold area, and the roads are treated with salt or chemicals to melt ice, it may have caused rusting holes to appear in the floor pan. Water spraying up from tires would enter through the puncture or slice and the carpet would wick the water in. It would take a long time to dry and give a musty smell after just a short time. You should inspect the floor pan from underneath the car. Look for punctures, slices and rust / rot. Clean and seal any openings found in the floor pan and firewall.

Fixed windows and glass in the car body are also sources for leaks. The is especially true if glass has recently been replaced. Many times, the back window leaks into the trunk or metal under the rear seat - and flows to the carpeted floor. Look in the trunk at the bottom of the rear window. Side windows can leak, too - so don't forget to look behind trim interior panels on the sides of the back seat. Your leak could be coming from the windshield, too - this will be harder to locate through the dashboard - but you may find water dripping from wires, etc. Look for evidence of water / rust. Clean and reseal body / glass joints when found.

Good luck!

weld brackets to teh seats and then bolt them through the floor ,if this is a panel van then check with local vehicle inspection station first as you may not be allowed to change the use of this vehicle under local law by fitting seats into a vehicle that only has a certificate of homoglonation for use as panel van

The battery is behind the passenger seat, hidden under the floor. Move forward the passenger seat. Then open the rear right door, clear all the floor mats on that area. You will find this somewhat square panel cover at floor level. remove the single #15 torx screw , lift up on that hole area while pulling sidewards. I hope you get lucky. Have a nice day. : )

hmm,, ok,, try this..

1.) look under the seat you will notice two sliding rods,, on this there are 4 brackets with bolts.. its maybe hidden under the upholestry,, any way remove the bolts,, slide any lift seat..

Remove the Cowl vent panel under the wipers. Each corner in the basin has a square drainage hole. Make sure they are clear with a blower or long wire. They get clogged with leaves and debris. Test it by pouring water and see if it drains under the fender. Drill additional drain holes if you want, at the bottom of this metal basin. On the back of this basin you will see a large rectangular hole where the air is sucked in for the heater. That is where the water gets into if the drainage is clogged. It then shoots through the vent under the drivers seat, aiming to the rear. that is why you get a wet rear floor.

I had a similar issue and found that the two rear drain holes for the sun roof came off and any water was running down into the trunk and also the rear floor was always wet. I pulled the rear of the roof panel down to expose the rubber tubes, re-seated them with glue so they would not come off again.
