Hello,

I tried out my AC yesterday.. As it hit 80 in Pomona, NY. But all I got was HOT AIR! I know I had had a clicking sound when the heat or AC was on last summer/fall. I think it was the blend door making the chattering noise. It allays stopped after 5 minutes.. I get no chattering of the blend door now..

So what to look for? the ETC module had been taken out about 5 years ago and the O rings replaced.

May have to replace the entire ETC module.
Thank you for the help

Ensure the compressor clutch is engaged and the lines are cold before tearing anything else apart. It's easy to check.

Exactly, make sure theres atleast 134a in the system. You might have acquired a leak. The accumulator has failed in mine, as well as many others.

Run the EATC self test to check the blend door actuator as it may have expired.

Check the A/C compressor, see if it's turning on.

Also check the system to verify that it has a full charge of 134A.

^^^what FBM said above.

Also, it's fairly common for the accumulator to rust out due to its stupid location. Fortunately, it's not an expensive or complicated repair. Mary had to have a new one installed in Phoebe a few years ago and the local radiator shop did it while she waited...I think it was under $150 all in.

Just went over my a/c system yesterday because mine doesn't work either. Drew a vacuum on the system and as soon as I shut the valve the gauge shot back to 0. Pumped a 1/4 lb of 134a in the system and found the leak in the evaporator core. Went on rock auto (before I realized they were now a vendor) and got a new evaporator core, receiver dryer, orifice tube and an ambient temp sensor (mines broke) for $95 shipped. So once you find out the issue with your car I would definitely goto rock auto.

This is just never ending.
The AC system in this car is a unreliable, defective POS!
Ford to this day continues to profits big time.
This is bullsh____!
Ford needs be slammed with a massive class action. All these failures need to be fixed free of charge! All Monies previously spent on repairing this garbage EATC system needs to be returned.

FKK YOU FORD!

OK, now that you got that off you chest....

What is wrong?

What is wrong FB? What--- you have not noticed the FORD AC system has a ridiculous high failure rate. The design SUCKS a really big....

I wonder how long it will be until another victim posts a problem on this site related to issues with the POS AC system.

The idiotic COT design is another winner.

I am amazed a law firm has not zeroed in on this.

F You FORD.

It's all about how the vehicle is maintained. My old man has a '97 for escort. He bought it brand new, had the a/c recharged once and has never replaced an a/c related part. My mom just sold a 2002 ford focus. Never had the a/c system touched and it worked flawlessly. As far as a law suit, there would be no case.

I checked out the system. The clutch engages as it should . The line under the hood is ice cold. The Actuator works fine as well.

It appears that the blend door may be the problem.. As the cold ac air is just blowing/ going over over the heater core .

Does one have to take the entire dash off to get to the blend door? Kind of a big job? Any easier way to solve the problem?

Thank you guys

Bought my MM new in 2004, has over 85K on it.
I haven't had anything major happen to my A/C system. I did have to replace the o-rings in the EATC. I will be replacing the BCM and the blend door motor for preventative maintenance ONLY. They are both working fine.

The COT is fine as long as you know how to properly bleed it.

If you don't like your Marauder sell it. No use having a car that causes you such angst.

If you decide to keep it we can help you with whatever issues you run into.

Before you do anything, run the EATC self-test. If the blend door actuator is bad it will cause a DTC of 024 or 025 IIRC. If no DTC's sometimes running the self-test "re-syncs" the EATC.

To replace the blend door actuator the dash has to be slightly pulled away from the firewall. The last one I did took 4 hours start to finish. The part is about $75.00.

If you need a new accumulator get a FOUR SEASONS Part # 83148 from Rock Auto as it is aluminum.

How do you do the test of the EATC?

How do you do the test of the EATC?

Found with a google search.............

Key on, engine running: Press OFF and FLOOR simultaneously, then press AUTOMATIC within 2 seconds. The EATC will have to run some tests and do some thinking. It may take up to 30 seconds. Soon it may display some codes. Write these down. To exit self test press DEF

EATC System self test error code list

024 Fault in blend door calibration during self test

025 Intermittent fault in blend door calibration

030 Self test indicates automatic temperature control sensor shorted

031 Self test indicates automatic temperature control sensor open

040 Self test indicates ambient sensor short

041 Self test indicates ambient sensor open

042 Ambient sensor intermittent short

043 Ambient sensor intermittent open

050 Self test indicates sunload sensor short

052 Sunload sensor intermittent short

115 Intermittent engine coolant temperature signal

125 Intermittent vehicle speed signal...

I DID the test of the EATC. Got code 024. Right after the AC came on and was nice and cold! Thank you Fastblackmerc for the suggestion! I guess it needed to be re-set!

I had the same issue so I tried what fast black mer told to do so I did it the error code 024 came up and I can hear the blend door working but it keeps clicking and clicking it came out cold air for about 5 sec then it came out hot again I think the blend root is broken is there a easy way to replace it

IMHO... the only way is to pull the dash forward and replace the blend door actuator. Part is about $75.00 and I recommend you get a Motorcraft one. Aftermarket ones are cheaper but have a very short service life.... they don't last long.

Try running the self test a few times. Might work.....

Blend door failure is 024 & 025

050 & 052 is Solar radiation sensor short to ground.

There is either a short in the wiring to the EATC or the EATC is bad.

Because the blend door actuator keeps clicking it won't stop after I did that reset code even if the heater or ac is off it keeps clicking it's annoying [emoji19]
