Broken seat My driver's seat is broken and I thought to use glue but it won't help

Probably has a broken or jammed lock When you position the seat try pulling/pushing the handle instead of relying on the spring to engage the lock. If the seat frame is broken remove it for repair or replace with another seat back

You will have to fix your panel with epoxy or get one from
salvage yard

I use crazy glue to put things in place
Then slide plastic water tubing from home depot over the
screw posts
Then epoxy -do all that on the inner damaged side
Takes a week to repair those type items or several

There's a bolt in each corner of the seat frame that goes thru the frame and into the floorboard. Remove these bolts, disconnect any wires, and pull the seat out. Same with the passenger seat if you want to put it on the driver side temporarily. The seat movement control will be on the inside though when you do this. Not a good idea, bit it can be done. Same seats, different actuator lever position.

Use a really good hot glue stick in a glue gun, or silicone caulk (will have to go 24hrs. w/out use) to set it back in place.

I sprayed cooking oil spray which lubricated the cable and it folded down

Take it back to the dealer .

If a fine pick won't work you could try super-glue carefully applied between the broken halves, or if the key is ferrous (steel) try a neodymium magnet (which you can find in an old hard-drive).

COULD BE SOMETHING ON SEAT TRACK NOT ALLOWING SEAT TO GO BACK..OR SEAT MOTOR MECHANISM COULD BE DAMAGED OR BROKEN.

Both seat heaters in this car are on the same fuse and relay. If one is working and the other is not, you can assume that the fuse and relay are okay. It could either be a broken circuit in the seat heater itself or a bad switch. Most likely it is a break in the heater element. I had this problem in my 2004 forester on the driver side. after removing the upholstry cover on the seat and some careful inspection I found two broken solder joints at each thermostat in the seat heater element. A quick solder job fixed the problem. The only real difficulty on the job was that the thermostats and associated connections are sandwiched between two layers of fabric and filled with hot glue. Careful probing with the end of a soldering iron can melt the hot glue away from the areas you need access to. A quick internet search will find you some pretty good directions on how to remove the seat covers. Hope this helps.
