Freeze fell out of motor while siiting in the yard

The piece of plastic you found was the clip that holds window to track. Sometimes you can change the clips most times need another window which has the clips installed. I would recommend a salvage yard

If you have the horn, find a mounting hole where it may
have been secured to & reanchor it

If it fell to the road side, get a used one at a salvage yard

Whooooeee!
Freeze plugs are about the size of a silver dollar. They are close to impossible to see, much less replace.
If there is any way you can do so, go to a junk yard, or a place where you can see an old motor that has been taken out of a car.
The freeze plugs are halfway between the top and the bottom of the motor, on the sides, and usually there are 2, 3, or 4 on each side.
Be Blessed.

The 'regulator' needs to be replaced with a known good one from a salvage yard (for a good price).

yes just make sure you use a brass freeze and apply sealant around freeze plug and tap in

If a freeze out plug feel out the antifreeze would run out as fast as you put it in.If this is the Quad4 style motor with the water pump housing betwween the motor and the firewall it is most likley in that area . the water pump seals are known to be a problem with this engine.

did the arm fall off with axle inside or alone . If it alone you can buy a new one at any auto parts store aswell as the tie down bolt if the axle is attached your going to have to make a stop at a honda dealer or scrap yard and get it used or new your choice Happy hunting

check with your local scrap yards. It'll be a lot cheaper there than at the dealer.

Hi my name is Allen!

When the window falls down it is because the cable for the regulator and motor broke. The only fix is a new regulator/motor assembly from the dealership, or a good one from the junk yard if you can find one.

For further asistance you may reach me at FixYa!

Yes that s true there is a ac pump and when the clutch starts going bad it will run and all the sudden just freeze up and it will snap belts right off... you just have to goto the junk yard and get a ac pump there not very expensive ..
