I was wondering if anyone knew where to locate an AC amplifier. I'm having the problem where the AC only stays on for about 10 seconds at a time and then shuts off. I've had no luck trying to locate one online. Does anyone know how much that part usually costs?

 

Easy way to do it is talk to your local Mazda dealer service department. Alot of them are happy to help with giving schematics and then share the insane cost to replace it.

 

Junk yars is your friend.

Also search this DIY section. You may be able to fix it.

 

theres a tsb for that... so if your still under warrenty its free at your dealer other wise heres a link to a file with a image and all the info for the amplifier(looking at it my self its way too expensive)

Found this on the GA site. The procedure worked, will test tomorrow as well.

Yeah, I know, I changed two things at once. However, the fan mod was more to be kind to the engine until I can afford a MM Cobb. I need shocks and springs to catch the bigger porches more than power.

The program your AC link from Glyphon on the GA club site.

The process:

To improve the performance of your A/C do the following:

1. Make sure the car is off AND the HVAC fan is off AND the A/C on/off button is off.

2. Press and hold the front defroster (on the left) AND air source (bottom) buttons

3. Continue pressing the buttons in step 2 and turn the key to ACC for 3 seconds

4. Continue pressing the buttons in step 2 and further turn the key to ON (NOT START) for 3 more seconds.

5. Verify the programming update by observing the REAR defroster LED blink 3 times.

6. Release the two buttons from step 2 and start the car.


When you turn on the A/C with the MODE button set to FACE and turn the thermostat to full COLD (max counter -clockwise setting) the RECIRC should automatically engage. In addition, the amplifier should put out colder air (~ 5-10 degrees F colder and not just from the RECIRC setting) and the compressor will not cycle nearly as often (which some of us found annoying).
Note: This programming change is not persistent. If the battery is fully discharged or disconnected the procedure needs to be repeated to re-enable the settings.

(quick note, hold the buttons with your left hand, turn the key with the right)
