@cny first gen 71 - Thank so much! I just bought a NOS part on eBay. Yours probably would have been cheaper. LOL I very much appreciate you stepping up. If the eBay item turns out to be wrong, I'll message you for sure. Thanks!

YES! Found it on eBay. Last one. NOS part appears to be correct. Not cheap but whatcha gonna do? Does not list it for a Monte Carlo (was listed under 71-72 Chevelle) and technically they should be different, but whatever, I'll take it! Thank you @MC1of80!

I need to replace the washer squirter nozzles on my 72 Monte Carlo Custom. They appear to be readily available in the aftermarket but the parts sold do not match what's on my car, which I assume are original. Attached is a photo of what I'm working with. The aftermarket pieces don't have the locating pin, are a different length, and different shape. I've called a couple of the aftermarket suppliers but finding someone who actually wants to figure out a solution is difficult. Does anyone know of a supplier or does anyone have one or two they would like to sell to me? I really just need one but would love a set. Thanks!

@72-CLASSIC_RIDE Hey Doug, I PM'd you my Custom info for your database. And yes, there is constant power at the harness connector in the trunk for the light. I ordered a new lamp assembly. Thanks for everything! Bryan

Sooooo... pretty easy diagnosis. See attached image. Wire was tucked up behind the brake booster. Looks like it got cut at some point and exposed the wire, shorting it out and burning the fuse holder. There is a constant 12v at the bulkhead connection so I'd say I just need to either a) fix the wire and fuse connector or b) replace the assembly. I'll probably just get a new assembly since it comes with the wire and fuse holder. The current one is pretty rusty and the wire is brittle. I feel bad for all of the time and advice you guys gave. Had I just looked at this first, it would have been a no-brainer. BUT, I really wasn't aware they were mercury switches so I was stumped on how to turn them off and on. That's how this all started. LOL Regardless, thanks again.

@72-CLASSIC_RIDE - yes, it is a Z03 Monte Carlo Custom and included the ZJ9 Lighting Group (straight from the build sheet). I'm going to check the inline fuse, test the connection at the mercury switch as you suggested. Per @Leghome's comment, the bulb sockets are clean, no corrosion. And per @Rob Peters's comments, the trunk light has a steady 12v supply but the lamp doesn't work (bulb tests good). The underhood has no voltage at the socket which leads me back to @72-CLASSIC_RIDE's comments about the inline fuse and connection at the bulkhead. I'm going to check these things but it may not be today. I'll follow up as soon as I do! Thank you very much!

@Leghome - this makes perfect sense. The bulbs are good, fuses are good, wires are connected. The housings themselves, especially the underhood light assembly are pretty corroded. I'm guessing the innards are junk. This car is mostly original (numbers matching, too). Just needs some TLC to get it back to 100% proper working order. Thank you!

My 72 MC has the ZJ9 Lighting Group which includes, among other lights, an underhood light and a trunk light. Neither of these lights work. My question is - and I've looked for the answer which I can't even find in the original factory owners manual - how to you turn those lights on and off? I've tried the courtesy light position on the headlamp switch which doesn't work and they don't come on and off with the doors. I have tested the bulbs and they are good. I've also tested all fuses, which are good. I feel like it's a silly question but I seriously cannot find the answer!

@Canuck - I hadn't noticed the difference in the placement of the sprayers from 70 to 71/72. Thanks for the clarification and now it all makes perfect sense.

Very interesting! So mine is correct as it is (once I get the cowl clips). I wonder why they abandoned the earlier 70 style routing? Probably a cost move. I really appreciate your pics and response!

Hello! I hope this is in the right category. Trying to understand the windshield washer hose routing for my 72 Monte Carlo. As you can see in the photos, my washer hoses currently hang free. Apparently there are clips that secure the hose to the lip of the cowl, and I have ordered those, but I'm starting to think that isn't correct for this car. I've seen photos where the hoses run through the two holes in the cowl and then through a hole in the firewall just above the wiper motor/washer pump assembly. I like this solution but as you can see in the photos, the firewall hole has been sealed up with some sort of filler on my car. It appears to be factory filler but I really can't say for sure. Can anyone confirm the proper hose routing for a 72 MC? Are the hoses clipped to the cowl or do they run through the cowl and firewall? I want it to be correct. Thank you!!

Thanks! As soon as I get the car where I want it, I'll post some pics. It's pretty nice now but I want to get it just right. 🙂

@Canuck - Thanks. Yes, after I posted I continued to research and found exactly what you said. I do have the electrical connector although it was unplugged (you can see it if you look closely at the picture). I understand why it's used and although I see it as purely an emission-related device, the car is a numbers-matching car and I'm trying to keep the car 100% original so I'll test it to make sure everything works and then hook it back up. Thank you very much!

Hello and thanks for having me! Recently purchased a numbers matching 72 Monte in very good condition. I'm trying to get it back to 100% original and functional. Trying to figure out what this part is. Mounted on intake manifold, next to Quadrajet carb. One vacuum line going to charcoal canister. Electrical connector was not/is not plugged in. Has two other vacuum ports that are capped. Can anyone tell me what it is/does and what the capped ports are for? Thanks!
