I have an '89 Civic DX 3dr Hatch. I have non-power windows and the regulators in both doors are messed up. I'm having lots of trouble finding new regulators. Everything I see is for a 4dr. I would prefer to get new non-power regulators but i'm willing to get powered ones if I can find them. My question is are the regulators for the front doors of a 4dr fit in the 2dr? Thanks in advance.

 

4 door regulators are definitely not compatible. You can still buy a new one for the left door here:

The right door may take some digging. I wouldn't mess with a used driver's door regulator since they take heavy wear from drive-thrus, toll booths, etc. but used should be OK for the right.

 

This is gonna be a headache. I'd totally buy the power window kit if I could find it!!!!

 

4 door can be made to fit actually.

You swap the rails from the manual regulator to the power one. I've seen a diy on it and found the regulators myself to do it one day.

If you find power locks in a 4 door, grab the front door latches and look rods while you're taking out the regulators. OEM power locks!

 

The rails are whats the problem right now. Currently the whole window setup is messed up.
