Hyundai tuscon 05. Reverse light doesnt work, bulb fine ,fuse are good and new switch installed. What next?

Reverse lights Terry, you will have ti check plug and wires at reverse switch, if all look good, probably a bad reverse switch.
Reverse switch usually on transmission.

Hey I'm having the same problem with my BMW 320d 2005 car. Fuses, switches ,bulbs are all fine abd reversing lights still not working . Please help me out

The reverse light switch is a mechanical device used to control operation of the vehicle reverse lights. The switch is designed to complete the circuit when reverse gear is selected allowing reverse light operation (manual transmission only).

You will need to either replace or adjust your backup switch, it is located on the transmission next to the shifter. Hope this helps, thank you for using FixYa!

Hello and welcome to FixYa!

If that's the case then it's definitely a reverse switch issue. If the reverse switch is faulty, the reverse light won't work even if the bulbs are fine. It is located underneath the transmission where it triggers when reverse is engaged. Have it replaced and you'll be good.
Hope this helps and thank you for using FixYa! Have a good one!

Hi there?
The reverse switch is on the gearbox on the left side next to the drive shaft. Unplug the plug and bridge the two pins with a pice of wire, turn the ignition on and select reverse. If it works like this then the switch is faulty. make sure the bulb is not faulty. Good luck...........

If the bulb and the fuse are good, (the fuse will affect other circuits as well, not only the reverse lights), your next stop is the reverse light switch. It is located on the gearbox and is a switch with two wires coming from it. Remove the wires and touch them together and see if the reverse light comes on with the ignition on. If they do, you need to replace the switch.

check the reverse switch as it's most likely failed. It'll be on the side of your transmission with several wires sticking out of it

Am I correct, the turn signal fuse is blowing when you put the manual shifter in reverse?
Let me know.
Regards

check bulbs first/ then you can check fuses usually under dash or in the engine compartment/Please rate my response thank you very much
