Electrical / Re: Door switch for courtesy lights on 1974 c10

« Last post by fiddler on April 16, 2026, 05:15:39 pm »

The barrel on the 74 protrudes 1/4 inch from the hex portion.  The plunger is self adjusting of course but on the 74 the 1/2 inch barrel is too long for the door to close.  I suppose I could "adjust" the point where the door closes over the switch with an inline shock adjustment tool, but denting that part of the door 1/4 inch is a last resort for me.   I am also planning on replacing the doors this summer and would rather not start out by denting the new door for the switch.

The door jamb switches are generally self-adjusting to length.  The switch sleeve inside the barrel nut is designed to slide inward toward the jamb the first time the door closes, setting the plunger protrusion to the proper height.

Electrical / Door switch for courtesy lights on 1974 c10

I have a titled 1974 chevy C10 with parts from a multitude of vintage.  The switch that turns on the dome light when you open the door (door jam switch?) has failed.  Turns out the spring has springed too many times and is now in pieces.  So I ordered replacement from   truck.  it's too long.  It appears the 1973 and 1974 model switches were shorter.  Does anybody have a source for these switches?  The tube after the hex area is proud by .23 inch.  Suspect was supposed to be .25 but is appears a bit mushrooomed by 52 years of opening and closing the door.  Thanks in advance for your help.

So I found the AC Upgrade post in the forum.  Answers all of my questions.  Sorry to bother again, but THANK YOU!  You have been most helpful.  I will put up with the noise until it fails and then do the upgrade.  This summer is doors and a hood!

Thanks for your reply.  So it appears there are a lot of knock offs for the sanden compressor.  Any idea where to get a "real" one?  Amazon has a string of them listed for like 130.00.  I would expect the bona fide sanden runs 300 to 500?  Did you use the full set of brackets or just the air conditioner bracket?  Is your compressor on drivers side or drinkers side??

raising the bed would be easier IMO.  With the bed bolts tacked to the bed would be a plus.

That's what I was thinking.  Just wanted to run it by yall to make sure.

It was easy last time.  Looked like this when I had it painted with the bed off.  They're kind of in a crap place even with the bed off.

That restore was a good write up.  18 years ago, wow...

It was a good write up until photobucket broke most of the internet   

I spent so much time making that.

Very Good.  Thanks fellas!

I'll use the silicone spray.  No paint in the truck's future.  She's still as pretty as she was back in the day except the wreck damage to the rear...lol

Hybrid compressor! 

Just kidding, it's either an A6 or an R4, axial or radial.  Radials are inherently noisy, more so when under r134 head pressures. 

The best solution is a Sanden SD508 + bracket kit and hose retro-fit, but it's not for everyone.  Alan Grove made my adapter brackets (https://www.alangrovecomponents.com/Small_Block_Long_Pump.htm), I made the hoses.  It's a lot quieter, and far more efficient.

i have a titled 1974 C10 Stepside.  Lots of different years of parts on it so I say titled.  The engine is a 350 with no port for a mechanical fuel pump so maybe an 80s block?  Anyway it is using R134 gas for cooling.  The compressor is stock.  I think the guy who replaced it for me years back said an A4.  Anyway it is cooling great but is annoyingly noisy.  Has been noisy since it's installation, but I am becoming more annoyed by the noise.  Is there an after market compressor that is known for quiet operation?  Any way to quiet down the compressor?  Any thoughts appreciated.  Thanks in advance for your response.
