Question about 2003 Toyota Matrix

1 Answer

My air conditioning is blowing cool, not cold air

I bouth a freon can with a gauge and if I did this right, it shows that no recharge is necessary. I took the cap with the H on it off and did the test. What else could be wrong with it and how much could this end up costing me?

Thank you.

    I have a similar problem but it has been a sequence of events. First, I had the electric window panel replaced on the driver side. Shortly after that my complete dash system that shows the gauges and speedometer went black. I took it to the dealership and they took it apart and said it would cost 900 to replace. The part is on back order, so they put the dash back together and it worked but only for a day. While I am waiting for the part to come in, my ac is now blowing only hot air. could these be related????

The "H" is the High Pressure side of the system. The gauge should be on the "L", or Low Pressure side. Here is an easier way to check for proper freon: Start the car, turn on the AC, and look down beside the radiator for a small circular glass "window", on a aluminum tube. This is where you can see the freon. If there are a lot of bubbles in the window, with the AC on, you need to add freon to the "L" side. Normal pressure on the "L" sied should be 28-32

My air conditioning is not cold?


First thing would be to check and see if the freon charge is low.
You would need a special gauge to check it.

My air conditioner is not blowing out cold air. How much freon do I put in a 2000 GMC Sonoma ?


That all depends how much freon it still has in the system, best way to check is with some a/c gauges, if you put to much it will not cool or could damage some thing, and if not enough will not cool right, used a/c gauges for right amount of freon, now if the a/c system is empty it takes 1.88lbs of 134a freon.

My air conditioning dose not get cold enought


This means you need to add more freon, you can take it in to get added or just go to your nearest auto shop and buy some with a connector and just turn your car on with your air conditioner on high, and connect the line to your can then to the low side of the air conditioner lines and hold the can up right so you let the gasses in, not liquid. when can is empty remove from low side and be careful disconnecting from can because freon is very nasty stuff and may still have a little in the can. and repeat until necessary.

Check engine light and air conditioning


I Think I Can,
You Might Be Blending Hot Air With A/C Cold Air And Being 100Deg Outside, Your Getting
Really Warm/Hot Air Inside,
Your System Is Charged w/Freon, The A/C Compressor Is On/Engaged,
There Are 2-Aluminum Tubes Comming From The Compressor, [In & Out Pressure]
1 Tube Will Goto The Front Condensor, Infront Of The Raidator,
The OTHER Tube Comming Out Of The Condensor Will Goto A Dryer,
[Aluminum Looking Cylinder] Bigger Aluminum Tube[s]
The DRYER Will Then Feed Freon To Your Evap-Coil Inside Your Car [Cool-Air],

OK, The Dryer Tube's, 1 Of Them Should Be Cool/Cold, Locate That Tube, A Thermometer
wrapped w/Alum-Foil Around This Tube,
A/C ON, [A/C Compressor Engaged]
If You See The Temp Is Around 50-55 Degree's Or Lower, You Have Cold Air,
If Not, Above That, Low Freon, Or A restriction In The System. [Comes Later]
You Have Cold Air, You Have Warm/Hot Air Inside Car/Vents?
You Are Blending Hot Air w/Cold A/C Air, Problem Is With Heater-A/C Blend Box
Under Dash. There Are 2 Seperate Coils Under The Dash,
1 For Winter/Heat, Other [Evaporator Coil] For A/C, There Is a Diverter/Flapper door
That, For A/C, Closes Off The Heater Coil, Or It Should, To Prevent Engine Hot Water/Heat
From Blending w/ Cold A/C Air.
Most Are Controlled By A Diaphram, Vaccum Controlled From The Heater-A/C Controller
On The Dash.
If You Can Select From Defrost Vent To Dash and Floor Vents, Most Likely you Have
a Bad Diaphram That Controls The Heat-A/C Flapper Valve.
Most Time's You Can Open/Remove The Glove Box And See It,
A Temp Fix, For Cold Air, Would Be Remove The Vaccum Line From That Diaphram,
And Plug It, Pull The Metal Rod Back On The Diaphram with a Needle Nose Pliers,
If you Get Cold Air, Take a Ty-Wrap, Around The Shaft, Secure It, To Keep The
Vent In The Cold Air Position.
Then You Will Have To Get A New Diaphram Installed, Most Time's, Can Be Done
Through The Glove Box Opening.

Now About The Restriction In A System,
You Will Need A Set Of A/C Gauges, Car-Off, A/C Off, Connect Gauges.
IMPORTANT: The Gauges Before Connecting Should Show Pressure In Them [Freon]
Either The Gauges Have Freon In Them Or They Are In A Vaccum.
Otherwise They Have Air In Them, Air w/Freon=BAD Things.
OK, Gauges Show Pressure, Gauges Not Connected To Anything,
Open Up Both Knob's, Blue [Low-Side], Red [High-Side]
Gauges Needles will Move/Equal Out pressure,
BOTH Gauges Should Read Same Pressure, If Not, Quick Fix, Remove Gauge Glass
Covers, Need Little Screwdriver, If Gauges Off By ie: 4 psig,
Adjsut Low-Side [Blue] By 2psig and other, by 2psig, [Split The Difference]
So Now Both Gauges Read IDENTICAL Pressure.
Close Both Valves, Blue & Red
Connect Gauges To Car, Car=Off, A-C=Off
You Will See Pressure On Both Gauges,
Low Side Shuld Be Around 75-95psig, Depending on Outside Temp, If Around 60 or less
need freon.
OK, BOTH Gauges Should Show SAME Pressure reading,
If There Is MORE Than a 4psig Difference Between Them,
There Is A restriction In The System,
a Plugged "Orfice Tube" [Filter] Part Cost $3.00, Servicing The Filter, Alot More.
Restriction Causing Might Be , Moisture/Air in System [Improper Vaccum On System During Last Repairs], Compressor Breaking Down [Metal, Black Goo Bul-up]

Hope You Get Some Cold Air Soon.

Air conditioning system is not colling the car ? what do Ineed to do ?


i need to know how is not cooling the car?
is the fan blowing air or is the blowing air not cold?
it probably isnt cold.lets try that.
put a set of 134a ac gauges on the system and verify pressures.if it has low freon you may hear the compressor turning on and off.if so for sure its low and you will just need to add freon.
go get a 134a fron fill kit not the conversion kit.
and begin to fill untill the comp stays on and air is blowing cold.then stop filling and enjoy.
do not over fill as this will cause it to not cool again.

AC is not working


Sounds like the A/C system just needs to be recharged. When was the last time you had this done? Just take it in to your mechanic and he can do it for you and if that's not it for some reason, then he will be able to find the problem but most likely you need more freon added.
