ac trouble... broken parts

[JubjubW]

I replaced some parts on my AC system.... but broke one of the hoses... its a line that leads from the actuator (drier) into the cab... does anyone know what this line is called?

and I stripped the nut on the coolant hoses that lead from the compressor to the orifice tube so that needs to be replaced... dammit all


-----

I can take a pic in the morning of the tube leaving the actuator to the cab in the morning....

I THINK its either GM part # 52464082

or

that oreilly link has the same type of fitting that screws into the actuator... but how the hell do you actually get them connected when neither spins?!

I would say 31 but i think thats just an O-Ring, but where the O-Ring goes is the tube I need

 

[SunlitComet]

if you are talking the tube where it enters firewall you have a serious problem that line feeds the evaporator and that is inside the hvac housing under the dash.

 

[JubjubW]

ya I know that... but with the purchase of a new evaporator does it come with this line?

I took the glove box out and started counting screws, bolts etc to do the work... looks like a weekend project for sure... sun-up til i pass out in the hoe then repeat

 

[SunlitComet]

here is a pictorial reference of the evaporator.

btw what do you mean by actuator exactly?

actuator/accumulator same thing right?


and the evaporator would be this part here right?http://www.autozone.com/autozone/parts/Everco-A-C-Evaporator-Core/1996-Chevrolet-Tahoe-4WD/_/N-j8ln5Z91sgw?itemIdentifier=79278_0_0_4147

if it is, that piece that connects to the accumulator, does that spin? if not how do you successfully get them together?!

No. But we know what yer talkin about.

The evaporator IS that part in your link but also the part pictured in your post that Sunlit Comet posted.

Yes, see that captured brass nut? That's was connects the evaporator to the accumulator. It pokes right though the firewall.

It sounds as if you broke the evaporator. Damn. Sorry.

ya, I guess the brass nut seized up... shoulda took a torch to it... but at least the hoe can run while I wait to repair the rest, we are getting a cool down here for a bit....

and just to be clear, I see two different evaporators, the one in the cab is the rear correct? and I am hoping I do not need the front one and just the nut on the regular hose got stripped

 

[SunlitComet]

and if you mean the clyinder object against the firewall when you say actuator/ accumulator the better name is receiver/dryer or accumulator/dryer.

the front and rear evaps are both in their own case and in the cab area. just different areas of the cab obviously.

Can I run the truck after taking the HVAC apart? I tried calling around to different parts stores, and they dont know which one I am in need of, so I wanted to take it out and show them

 

[SunlitComet]

Kinda hard if you take the compressor out. The drive belt can't go back in then.

 

[JenneK]

and I am hoping I do not need the front one and just the nut on the regular hose got stripped

No, you need the front evaporator core. But then again...what hose are you talking about?! Maybe you should post a picture of the damage.


Listen, to do this job you need an evaporator, a new accumulator, orifice tube and all new O-rings. I also suggest new schrader valves but the guy who purges, flushes & recharges your system after you replace those items can evaluate them.

Can I run the truck after taking the HVAC apart?

Well, you have to remove the dash, steering column etc. No sense in removing all that to get to the evaporator, then put it all back together just to take it apart again. It's a pretty big job.

BTW, no need to remove the compressor to redo the evaporator. Not sure why it was mentioned...

 

[SunlitComet]

expansion valve? i assume you mean the front orifice tube.

i mentioned the compressor just in case he takes it out. just in case.

My a/c just went out on my hoe... front clutch. They can't find a replacement part... 3 days later... still hot... no hoe. I hope they get it done today... $700 later.

The whole system was changed just 1 year and 1 month ago... 1 month past it's warranty. I think Global was the name of the manufacturer... it was just under a grand last year.

 

[SunlitComet]

you can replace just the clutch. it is about $100 average.

 

[JenneK]

expansion valve? i assume you mean the front orifice tube.

Correct and corrected.

Expansion valve = Receiver/dryer
Orifice tube = Accumulator

They always get mixed around in my brain.

 

[JubjubW]

O snap, I wasnt aware that I needed to take out the steering column too!

I have a new compressor and drier on right now, just need new hoses and evaporator

 

[SunlitComet]

yeah the steering column clamps the dash between it and its support structure in that area.

If I were you I'd buy more different parts of chevy other than a new AC and stock them up as replacements for any of your future car troubles
