Hatch pull down switch alternative
Hi friends!
As you may know the switch that limits travel and determines the rise and fall of the rear hatch motor is no longer manufactured and is difficult to acquire. This is why I have developed a solution that I come here to share with other owners. It is an economical solution and it works very well. It only requires a switch you can find on ebay for a dollar and some ability to build an L-bracket and some soldering. I'm attaching photos. I will be happy to answer any questions!

Excellent solution to a problem that comes up frequently on this site.
The only thing I'd add is to source a high-quality switch rather than a cheap no-name item. Electronics components suppliers such as Digikey https://www.digikey.com/ sell switches that are tested to last for thousands of cycles without failure.

Re: Hatch pull down switch alternative
Interesting. Since the assembly differed between the years, and the 92 unit is NLA, any idea how this solution would work on a 92? I have purposely NOT opened the hatch on our B4C since the last time I did, it took a couple of days to get it to pull back down.
I'd like to do the headliner in this car, but the hatch is the best way for it to come out and the new one to go back in. =8-0

Re: Hatch pull down switch alternative
Have you identified that your T-switch/Reversing switch is bad? Depending on the condition It is possible to repair them.

Wow didn't even notice that lol, nice too meet another O-state native. Greater Cincinnati F-body Association im going have too check you guys out when the weather gets warmer. As far as making sure the T-switch/ Reversing switch being bad, I don't think its completely bad because when I open the hatch the motor will come up. But when i close it won't pull down until i drive around and hit a couple bumps then it will magically pulls down lol. i was thinking maybe the solder had some cracks in it causing it to loss connection.
