son of a bishop -- seized compressor

[MAKG]

OK, now I'm pissed.

The parts store is not a problem. The shop is.

They claimed it takes an hour EACH to recover refrigerant, flush the system, and remove the orifice tube. Bull freakin s**t. Especially the last one (a proper flush has the orifice tube already removed, so the additional effort is ZERO). So I told them where to stick it. As for an hour to recover refrigerant, well maybe if they are evacuating for a recharge, but my estimate is barely over 15 minutes.

Of course on Monday when I made my appointment, they said an hour. It's Friday at 8AM (after I've dropped the vehicle off, of course) that it changes to 3 hours.

So, I lost a week. I'll have to shop around next week.

For $300, I can buy all new parts and skip the flush entirely.

 

[skippy]

fixed yet?

 

[RobbieD]

Well, you did the right thing walking away from the first shop. Good luck on finding an alternate.

 

[DesertStorm]

just by the $40 bypass pulley kit, then use the 2-55 a/c. I have used no a/c in 106F weather, I am still here to write about it. That is 106F with 90% humidity down here in the south, not in the desert. Notbad at all.

 

[MAKG]

Not just no, hell no.

I'll junk the truck and buy another before I start disabling equipment. The defogger is really pissing me off.

And FYI, you don't need a bypass kit to disable A/C. It works like that RIGHT NOW with the compressor unplugged.

for what my opinion is worth to you, i would suggest replacing the lines if they are on the older side(ie original), and for the money vs a shop doing the work just buy all new parts and get the job done yourself, then atleast u know that u really did everything and not have a shop SAY they did everything.

 

[MAKG]

I've certainly thought about that.

And if I can find the time to deal with it, that's a likely possibility. $300 isn't THAT expensive an A/C repair.

Especially since I can't get a straight answer (that I can take seriously) from anyone about whether or not they can flush a parallel-flow condenser. It doesn't look easy to me. The only unequivocable answer came from a guy who also claimed the orifice tube protected it from any of the compressor debris.

As for trusting the shop, I routinely inspect shop work (it's saved my butt a few times, like when an alignment shop left the tie rod adjusters loose, and a "rebuilt" mail order head that came back severely bellmouthed, with a very quick one-angle valve job, and with no shims). I can blow a little brake cleaner into each component and see what comes out.

FYI, the only original A/C parts on this truck are the liquid line and the pressure switch. The evaporator, condenser, and compressor line assembly have all sprouted leaks at one time or another.

 

[mhughes165]

if you cant get a stright answer from a shop then id just bide your time until u have the time todo it yourself, luckily enough it is winter and it isnt too hot in cali right now (i lived in antelope outside of sacremento for 5 years) and im certain you will save money by not letting the shop touch the truck on this one.

 

[MAKG]

Well, I use A/C year round, for much more than just cooling. It's a very good dessicator, and where I live is considerably wetter than Antelope Valley. We got 30 inches in January, and the driveway probably won't be dry until April.

But now I'm sidetracked. I spotted an FN field mouse in the 'sploder yesterday. I suspect it got in through the outside-air door, as the blower motor is making sounds as though something is in it.

 

[mhughes165]

have fun with that mouse, u know if theres one theres got to be a few more. i never quite figured out a good way to keep them out entirely as one day i was drivin my truck and one peaked at me through one of the dash vents.....needless to say i was slightly perturbed and tore the entire dash out, they all got away but i still dont know how to make sure they never get it again

 

[skippy]

about that mouse,catch and release or summary execution?that mouse have a prayer?

Sure makes changing the plugs a helluvalot easier to get to. And the bypass pulley looks soooo trick. Heat will defrost just fine. No need to de-humid the air too, ure just wasting gas doing that. I hate a/c on a truck. It is the first thing I hack away at. You get a lot better cooling capacity without the condenser restricting airflow to the radiator. I love my 4oh better than my own comfort.

But seriously, to flush the condenser go to an commercial a/c supply house and get some stuff called SUPCO88. It is an oil additive that removes all gunk from the system. It takes care of acid formations, sludge and all that other nasty stuff. If you dont change the condenser, run this through and change the oil in the compressor after about 50-75 hours of run time.

if mike experienced a burn out,and runs the supco 88 or acid away it will put all the gunk in the drier,and he'll have to change the drier too,not just the oil.sorry mike,i vote for complete replacement of all components.only way to buy complete peace of mind.i too run year round on defrost w/a/c in work truck,it's more comfortable to me.

If it were mine I'd spring for a new core. There's no way to effectively flush a parallel-flow core without removing the ends and flushing each path by itself. To check the core for crap, pour some solvent in it, let it sit for a few minutes, shake, then dump it through a coffee filter. If you find anything signifigant, the core is condemned.

The orifice tube will only catch stuff after it passes through the condenser core, which means you can still get a good amount of timebomb material wedged into the crevices. If a chunk of that stuff lets go all at once, that teensy little screen on the orifice tube will either get plugged up right away, requiring more AC repairs, or burst, letting metal circulate through the shiny new compressor, requiring lots more AC repairs.
