omg, thank you very much. i was going by the first diagram and thought the switch was by the passenger trunk side corner. did not know it was in the arm assembly. again, thank you very much.

Jenpm

finally got to fixing the switch. so happy that I did not had to take apart the roof and rear window or rear shelf




. 4mm socket to get loosen screw which was slightly corroded. used surgical forceps to reach.

Looks like you had to do quite a bit of digging to get to it. So was it the switch that was bad or was there a mechanical failure? Are you up and running now?

Jenpm

Techstream confirm bad switch. Problem was the top closing and getting stuck, was only rare but annoying and hesistant to open the top when weather was beautiful in Florida. Just wanted to show the pics and appreciate the support forum members

Glad that you got it fixed. Thanks for posting the pictures.

Hi. Have same error. I'm about to order the part.

Two questions, is the part number 84742-24080 (limit switch no. 1)? And for North American models, it is on the driver side, right?

Many thanks

Jenpm

no. Part in located passenger side convertible frame. I have to look up my past order

Jenpm

sorry, had to look up the part. that is the part for the error code. location of the switch is at passenger side.

Awesome, thank you.

As of now, roof not opening. Usually it's intermittent. If I get the part and roof doesn't open, can I replace it without roof opened?

Jenpm

Roof have to open like my pic to get access. With top closed, The frame is in the quarter panel/window.

This sounds crazy, but run your car over a speed bump without slowing down. Then try the roof. If the switch is misaligned, this may jar it back in place. It is not a long term fix, but it might work to get the roof down so you can fix it.

Otherwise you can google how to lower the roof manually (it might be in your owner's manual)

How to manually open roof.. not sure it's applicable to your year.. but should generally be the same.

HI. Ordered and received part 84742-24080.
It is not the limit switch roof position 1. It's limit switch for tray package no. 1 that is located same place but the driver side.

​Seems the part number for limit switch roof position 1 is 84742-24050.

Can you please double check the number and let me know if it's actually 84742-24050? I need to reorder but want to make sure.

Thanks
