A/C woes.

Postby ZORT » May 17th, 2004, 10:34 am

Ok guys i know a lot of you may have, like me, bad run in's with these A/C shops so here is what happened with me.

A/C stopped working no cold breeze.
Check to see if the a/c clutch was engaging - nope no clutch engagement.
Check the relay - swap it with the condenser fan switch relay. Fan coming on then relay good. Swap back.
Bridge the relay to ensure the clutch will engage. The relay pins will look like this: l l
-
-
Bridge the bottom two. Clutch engages. Circuit good.

So why the clutch not engaging... Pressure switch on the dryer. If you unplug the pressure switch, you will see two pins on the dryer looking up at you, you should get continuity across the terminals if there is no continuity the system does not have the correct pressure for operation and thus not allowing the clutch to engage.

Went to the A/C shop and they hooked up the pressure gauges and as expected the system had no gas, I had sprung a leak from one line rubbing against another and the aluminum corroded.
They took out the dryer and it was going bad, when you shake it you should not hear anything moving, if you do it is going bad, so we changed it. Next was the expansion valve on the evaporator, basically when the dryer going bad it usually clogs the expansion valve so that was changed also.

Vacuum and re-gas:$350 (new gas 34)
Dryer new: $100
Expansion Valve: $100
Labour: $100 (Bending and re-routing line to avoid this problem and repairing the lines)

So there you go simple. Tell me if I get wood by the cost. :)

Also most of the Hondas give expansion valve problems and most of the time the dryer will need changing at the same time. If the car’s A/C system works fine but the car cools sometime and then stops cooling but the clutch is engaged then the expansion valve most of the time needs changing.

These are simple test to keep you mind at ease at the shops. If any one can give more info please do.

Where did u get the expansion valve??
Who did the work on your car??
Also if the expansion valve is changed is it necessary to gas or can the valve be changed alone.

Check the guy behind grand bazzar. TONY. He did the work.
The valve cannot be changed alone. You will have to re-gas. A/C is a profitable profession you know... hmmm

It not gone yet...but it is on its way out...and the noise not stopping as RPM increase, is just that the 'click' is more frequent so it harder to hear as its more of a constant noise.

start sourcing one soon...if you buy one FU now, you can still get it PROPERLY rebuilt before your current one dies.

question
is the compressor on the vehicle designed to run the new r34 gas
some compressors need to stay with the older type gas for best performance

SR... a/c places will not fill an R12 compressor with R134a gas... they will tell you to revamp the system to suit... which is costly... otherwise you''d need to find someone that still has R12 gas.

Zort... where you got them prices meng ? They are cheaper than the place I normally go.

Check G. Bobb in St. Joseph, Eastern Mn Road opposite the WASA Entrance.

Paid $800 to change a compressor, supply and change dryer, vacuum, regas R134.

I lost faith in them fellas behind Grand Bazaar ever since the "price of gas suddenly went up". :fist:
