Customer Question

I have an 07 rx350 and my turn signals will not work. The hazard button turns on all turn signals fine but, the turn signal switch at column won't. While working on it I accidently left dome light on and had to take off battery to get it charged. Upon installing, I'm noticing I have to reset windows. Also, now my ac controls won't work.

Hello and Welcome! I'm Billy and i will assist you with your inquiry. Feel free to ask if any further info is needed.
My apologies for the delay, thank you for your patience.
Let's start by resetting the windows:
1. Disconnect the negative battery terminal for 10 seconds.
2. Connect the battery terminal.
3. Turn the ignition switch ON.
4. Halfway open the power window by pressing the power window switch.
5. If the AUTO UP/DOWN function operates normally, reset operations have been completed at this time.
If not normal, follow steps below.
6. Turn the ignition switch ON.
7. Halfway open the power window by pressing the power window switch.
8. Fully pull up the switch until the power window is fully closed and continue to hold the switch for approx. 12 seconds after the power
window is fully closed.
9. Check that the AUTO UP/DOWN function operates normally.
As for the A/C i would first check for any blown fuses, and if the fuses are good, you need to have the system reset using a toyota scan tool.
Now for the original turn signal problem, we need to check the signal switch, at its connector, and replace if necessary, i will include the troubleshooting details:
