Yep that would be sweet. If only...

Re: 1972 Chevy Pickup Project.
 

So back to the salvage yard this morning I went. I picked up a new wiper switch. I brought it back looking up and the wipers are working like it supposed to now. I tried to find a clock Spring while I was there but everyone has already taken all of them. So when I got back I wanna head and took my clock Spring out and took it apart and sure enough it is ripped at both ends.

Re: 1972 Chevy Pickup Project.
 

Well glad that fixed the wipers. New clock spring and you should be set!

Re: 1972 Chevy Pickup Project.
 

Well here is what I have decided. I picked up a different steering wheel yesterday and I put it on the truck. This morning I ordered a new 7" touch screen with navigation. I think I am going to like this route a lot better

Re: 1972 Chevy Pickup Project.
 

That should be super nice!

Re: 1972 Chevy Pickup Project.
 

Ok I just found another problem.....I took the truck for a drive (man was it fun) and the issue is when I put the shifter into park it clicks the clicker for the blinkers. It dont flash any lights but I can hear the clicker click 4 or 5 times. I can duplicate the results anytime I put the shifter into park. even without the engine running. anytime you shift back to park it clicks. any ideas? thanks

Re: 1972 Chevy Pickup Project.
 

Have you replaced the multi function turn signal switch/wiper switch

Re: 1972 Chevy Pickup Project.
 

Yes thats how I fixed the wipers. That was my thought as well that it was causing the problem but I put the old one back on and it does the same thing. everytime its put into park it clicks.

Re: 1972 Chevy Pickup Project.
 

Does it click both signals or just one side? Is hazard switch stuck?

Re: 1972 Chevy Pickup Project.
 

it actually dont light up any lights, it only clicks the clicker that in the fuse box. Its the same clicker that clicks when the trun signals are presed.

Re: 1972 Chevy Pickup Project.
 

Let me look it up for you

Re: 1972 Chevy Pickup Project.
 

thanks

Re: 1972 Chevy Pickup Project.
 

Are you running the Tahoe body control module

Re: 1972 Chevy Pickup Project.
 

yes

Re: 1972 Chevy Pickup Project.
 

Do you have door switches hooked up and wired to bcm so it knows when doors are ajar

Re: 1972 Chevy Pickup Project.
 

No there are no door sensors hooked up.

Re: 1972 Chevy Pickup Project.
 

Does it click five times after the key is shut off or with the key still in the running position

Re: 1972 Chevy Pickup Project.
 

While it is still on. As soon as you put it into park it does it.

Re: 1972 Chevy Pickup Project.
 

I don't know if it will fix that problem or not but you definitely need door switch signals going to the body control module. If your truck does not have door ajar switches it is not that hard to install I did it on my project

Re: 1972 Chevy Pickup Project.
 

Do you know which wires from the bcm are for the door adjar?

Re: 1972 Chevy Pickup Project.
 

I'll look at a wiring schematic for you. You can also wire it so your dome light comes on when door is open. Your door switches will provide a ground when door opens.

Re: 1972 Chevy Pickup Project.
 

I found the wiring diagrams for the bcm I believe. It seems I need to show the rear doors closed as well as the rear hatch. Now that I think about it my instrument cluster keeps saying replace lift gate fuse. but i find no such fuse.

Re: 1972 Chevy Pickup Project.
 

Yeah just trick bcm to think there closed except for front doors.

Re: 1972 Chevy Pickup Project.
 

i grounded the wires from the bcm that are for the rear doors and the rear lift gate. Now the instrument cluster says those 3 doors are open. Which wire goes to the dome light? I need to hook it back up so I can test if its on?

Re: 1972 Chevy Pickup Project.
 

Any luck with the wiring issues you were having

Re: 1972 Chevy Pickup Project.
 

I have not had a whole lot of time to work on the truck this past week. I did end up buying a shop manual with all the wiring diagrams in it. If I leave the wiring off to the doors the bcm shows them as closed. If I ground the wiring to those doors it shows them as open. I am still getting the message "replace rear gate fuse". I did manage to get the brand new front and rear windows and seals installed. Thanks for checking on me Jason.

Re: 1972 Chevy Pickup Project.
 

So If I understand what you did as far as the door sensors you simply just removed or did not connect them to the BCM? Correct?

Re: 1972 Chevy Pickup Project.
 

That is correct, but.....I may have to hook them up for everything to work right.

Re: 1972 Chevy Pickup Project.
 

Once you get to that stage let me know what you ended up doing so I can repeat...

Re: 1972 Chevy Pickup Project.
 

will do

Re: 1972 Chevy Pickup Project.
 

Forgive the 5 month necro-bump. Has there been any further progress on this awesome project?

Re: 1972 Chevy Pickup Project.
 

Well this is a bummer, I'm looking to do a similar project but not many of these builds have been completed. I hope all is well with the OP, last post was in 2018.
