2012 Acura mdx turn signals and rear wiper stopped working. The hazards work though. It has a aftermarket remote start that if you lock the doors it will keep starting and turning off the car until you unlock the doors.

Yep, I would remove the aftermarket remote start, (those fail all the time) and wire the harness back to stock. Next, check the fuse # 10 and #11 in the fuse panel under the hood, also check fuses # 20, #21 and #7 in the fuse panel inside the car on the left side of the dash this guide can help:

If the fuses are good chances are the fuse panel inside the car is bad, it has a MICU that is intergraded into the box which goes bad and stops the blinker and the wiper system from working. We might be able to do the CAN scan which will show us a code for the panel to help confirm the issue.

Please let us know what happens.
