Last year rear hatch popper quit working.
Replaced latch ass.
Did not fix the problem.
Now both side door poppers don't work.
Any good idea's out there. thanks.

Welcome
Dumb question but have you checked the relays and fuses for the doors and hatch ?
If you replaced the hatch latch assembley, did you check to see if there was power in the harness to that assembly ?

 

Fuses relays buttons

Has anybody put a fuse in a spot that was empty? Position #11 must be empty.
The access panels are on fuse #10 under hood. The relays are on a fuse block in the right rear qtr panel access. There is also a relay on the left front wheel well under the hood.

If the car is a 2008, has the battery been out or dead for more than a couple of minutes? 2008 models have a problem with RCDL memory.
Has anybody used a computer to try to fix anything. The Panel doors need special attention that most technicians don't know about.

I guess you know There are no electronic poppers, just locks and the rubber gasket does the popping. Is it possible the panels are just sticking? There is a TSB concerning adding a washer to the check link.

 

For the rear hatch, you replaced the latch but not the pressure switch in the rear beauty bar?
