I've known for years that my cars A/C control was leaking vacuum, but I never bothered to replace the a/c selector mode switch, as it always worked sooner or later.

Well, now its finally given up the ghost and I'm stuck on the defrost.

So I searched this site, and read up on what I need. However- when calling around for parts from local suppliers (napa, o['rielly, autozone, GM dealer)

What I'm looking for cant be found in stock anywhere in the world. Four Seasons, Murray, Everco-- all out of stock everywhere.

I'm looking for the GM part # 16032395 Which is also known as/looks like one of These


I'd really like to buy a new one, rather than a junkyard part, as I haveno plans to sell my car....ever. I'd even buy an all new heater control unit if needed...but also cant find one of those either.

Anyone have any thoughts where I might be able to go to get a new a/c selector mode switch, or an entire a/c heater control unit?

 

are you sure that the vacuum hose under the hood isn't disconnected or cracked?

 

No leaks under the hood.

You can hear the hissing right at the back of the control while inside the car. I just like things to work the way they are supposed to work.

Whats disappointing is that no one has these in stock in the aftermarket. Their like hens teeth from what I am finding...


I try to take care of the car. I've owned it since ~1994. Its still in nice shape as far as i'm concerned. Not perfect by any means, but normal wear and tear is starting to show in the common places- Drivers seat is starting to tear on the bolsters from getting in and out, the drivers seat belt plastic is broken.

I just now (today) had to replace the original alternator as it finally gave up the ghost last night coming home from work.

Other recent repairs this year have been tires/shocks/struts/transmission mount/idler pulley/heater control valve, as well as all fluids. I did carpet and a new top a couple years back.

 

Yeah AFAIK you're not going to find that new anywhere but GM; and that's not bloody likely.

Fortunately ALOT of vehicles use the same one. Shouldn't be too hard to come up with something at yer local buzzard.

They're not hard to take apart, lube with silicone grease ("dielectric" grease works fine, and run for another few decades. In fact that might be all your existing one needs. Take a look.

 

I might try the grease, since I'm probably stuck with a junk yard part.

I'll probably get around to it in a week or so- so far, it looks like the weather will be nice for the next week or so which will allow me to put the top down and skip the A/C.

 

You mean this -

This is a local supplier over here, he ships worldwide afaik.

 

I'll try to contact them in a week or so, after I've had time to tear my car apart and get at the part to confirm the bad switch.

If they've got it, im buying it. For whatever reason I cant seem to find them in the US.. not sure why.

 

I was alerted to the need for this item by a customer. I have some of the GM 16032395 that I have refurbished and tested in stock. I came upon this old thread and thought I'd let everyone know.

I just bought one of these last week, GM 16032395 from TDS. They describe them as "refurbished", but they look and operate as new. It also came with new screws, and the two small, round retainers that fit onto the pins to retain the vacuum lines to the control panel. I finally have a leak-free A/C control panel!

 

I need one again

 

There’s one on eBay

 

I don't know if this can help you or not.
