SOURCE: Neither my heat or a/c works and when I try to

does the air temp change when you try to blow ac and or heat?? if it does change from cold to hot at your discretion and it is still fogging up you may have a leaking heater core and in which cases the "fog" you see on the windshield is actually antifreeze blowing onto the glass from the leaking heater core.

A/c condenser leaks need directions to replace

First things first.

Make certain you have all the parts and tools required before you begin...
You will need a torque wrench to properly replace the unit.

Having said this and not knowing which model or year your Hyundai vehicle is. I will say that if your vehicle is not already running on the R134 refrigerant, this would be a good time to make that switch over and upgrade.

If this is what you are considering, the Air Drier/Accumulator would also need to be replaced at this time. This is the cannister usually nearest the firewall with the two A/C hoses/pipes coming from it.

(A/C Compressor - Drier Accumulator - New refrigerant)

You should completely disconnect your battery.

Removing the A/C Compressor will vary in difficulty depending on it's location.

Some A/C compressors are located on the top of the engine, or just off the side and are really easy to exchange. While others are located in more difficult to reach areas, like underneath.

Depending on where your's is located, you may find it easier to first disconnect the hoses on the back as well as the bracket supporting the rear. Then remove the bolts from the from bolt tabs and proceed to manuever it away, as best as possible..

Same process for the old Drier/Accumulator cannister. Dosconnect wire connector, unbolt hoses and make note of it's position, to help with installing the new cannister properly.

Some A/C compressors have a SWITCH. This is generally located on the rear head of the A/C compressor and looks more like a cap that is screwed onto the switch cavity plug. You may note this once you remove your old compressor. Remove that and keep, you will (most likely) need it to use on the new compressor.

I mention this because new compressors rarely come with a new switch and all too often people will install their new A/C compressor without swaping that switch from the old to new compressor... In which case, it will prevent the compressor clutch from actually engaging. Hence the result would be no cold air being detected, and a process of chasing fuses and relays begins in order to try and find out what it is and why it is not working...

(***Hopefully you have read and noted the above NOTE, YES, it is that Important***)

There will most likely be instructions in the box with your replacment compressor and I am assuming that you are replacing with new as opposed to used parts.

Installing the new compressor is in the reverse order. Once everything is tightened up and bolted back together.

As you begin filling with the new refrigerant, take note of any air leak or hissing sounds right away. If any noted, make proper adjustments prefore proceeding.

Hopefully you will have found this useful

Good Luck and Happy Motoring

Need to change to a a/c retro fit do i need to change dryer or filter if so how and where is it'' on 10 90 chev z71

yes change the accumulator /filter drier and the orifice tube the orifice tube is on the high side line going to the condenser and the accumulator is on the fire wall passenger side but this system needs to be evacuated before this is done its against the law to release these gasses into the air so youll need a recovery system to do this dontforget to replace the seals also

96 lhs has drier leaking can the seals be replaced , do i need to remove/ replaced the drier ?

Yes you can replace the seal only,Its only a bag in there that attracts moisture, do you need to replace it not really,Just replace the seal and ensure there is no leak.But if you open the system you ll need to draw out the air before you refill with freon

How much oil needs to be added to a/c system after replacing with new compressor and dryer on 99 Olds Intrigue 3.5L engine?


Feb 21, 2011 | 1999 Oldsmobile Intrigue

1 Answer

The a/c blows and the compressors on. at least the clutch engages its just not cold

If you know the system has the correct amount of freon and it does not blow cold usually this means that the accumulator, or sometimes called the drier bottle is full of moisture. They only hold so much.Yours being an older car it happens.In which case the accumulator must be replaced with a new one. All freon must come out to releave the pressure. The drier must be replace with a new one,includeing the orings or seals that seal the drier, then the system should be evacuated with a vac. pump and reduced to negative pressure. It should hold this neg. pres. for a few hours to show if the system has a leak.Then new freon added at the exact proper amount for that car.
I hope this helps you.

This is ''pops'' moore again!trying to save a $ You helped me before on the firing order.went to a/c guy.he tested system,said evaporator was bad and needed to be changed.his est.was my first born and a...

I assume he used a leak tester and found a leak in the evap which is inside the plenum housing. Need to remove the plenum to get access to the evap. big job. If you are technical, you could remove the plenum assembly and let him replace the evap & then let you out the plenum back in. Then take back to have him evacuate and recharge system.
