Re: Door Ajar Switch Spacer

Hi John,

Thanks for checking your '68 door. I would like a picture of the contact pad spacer too. I will try to check if a Bowtie '68 has this feature too.

There was no year given in the original post but I now see from the profile that it is a 68 car. My memory tells me that 70 and up cars could be seen w/ the spacer but can't say for sure on the 68/69 cars.

1970+ Corvettes used a grommet behind the door jamb-mounted switch. This grommet was not used for 1968-69. The grommet was GM #3977822. From what I can find, it was a piece that was NEVER available in SERVICE.

I asked a '68 Bowtie car owner to check to see if there was a spacer pad on his door for the door ajar switch and he said there was no pad. Just a worn place in the paint where the door ajar switch makes contact. Looks like it could be a '70 and later addition.

Original '68 owners would be welcome to comment about this too.

Terry,

if you look closely at the tube, it has a slight "crush" to it. By this I mean the tube is slightly out of round and when installed, the door would push the tube into the base and the out of round tube would jamb into the in the base. It was desigend as an iterferance fit. What you should do is to push the tube back through the base. Then ever so slightly put the crush back into the tube. Then they will self adjust again.

You guys are getting me to reveal all my tricks I have used over the years .

Hope this helps, Rich

This is for the courtesy light switch. Check the inside of your door and see if it has been dented by the original switch I have had to repair the insides of doors to bring them back to the original shape to make the adjar switches work.

I'm back home and finally got pictures of the pads that I have on my 68 for the door ajar switches. Both side are the same. I believe the paint in the door jam area and the weather stripping is original.

Well I learned something new today.

John,

Thanks for the pictures of your door. Do you know the build date of your '68? Perhaps this was something added during the production run. On the door of '68's, there are indentations of where pad could be placed. You can see them in your first picture. Why are they there if not as a guide for some type of pad?

I can't see any real difference between the switch contact surface on the 1968 door and that on later doors, so I don't think that anything different was done on the 1968 door to accommodate the cushions.

What I can't figure out from the pictures is if these cushions were hand-fabricated at the factory from stock or if they were actually manufactured by a supplier for this, specific purpose.

My car has an April 18th build date.

I agree with Joe that the contact surface on the 68 door does not look and different than my 69 that I have attached a picture of. The indentation is only there to get the door and door jam surfaces parallel to each other.

The foam appears to be similar to what was used to seal the radiator openings at the core support, so they could have easily been made from these pieces on the assembly line. They are 1 inch square and 5/8 inch thick. They do have nice even cut lines as if they were die cut.
