Avoid a trip to the mechanic by trying to troubleshoot problems yourself in your Mazda 6. While air conditioning problems are common, they are often quite simple to diagnose and even fix. Take a few easy steps to try and determine the cause of the air conditioning problems on your own. Start the car and turn the air conditioning on. Allow the engine to run a few minutes so the air can cool. Check to make sure you have the proper buttons selected. This simple step may uncover the root of the problem. Adjust the climate controls. If they seem to work fine but have effect on the air then the problem is probably a simple blown fuse. If the controls do not work correctly then the problem is probably with the
control panel. If you cannot hear the sound that accompanies turning the air from low to high then the problem is likely with the blower motor. Get into the fuse box in a Mazda 6 from the interior of the car. Open the passenger side door and pry off the trim panel on the right side edge. Use the chart on the inside of the fuse box cover to find the right fuse. Pull out the fuse and replace it with a fuse of equal amperage. Disconnect
the negative battery cable before getting to the control panel. Remove the center panel unit. Unscrew the four screws, one in each corner and pull out the climate control unit. Remove the blower motor if it is not properly working. After disconnecting the negative battery cable, drain the engine coolant into a container for reuse. Open the glove box door and remove the clips to pull the glove box out. Find the blower motor behind the glove box.

Oct 21, 2012 My A/C stopped blowing cold air yesterday. I checked it today by opening the hood, starting the engine and turning the A/C switch on and off, and i do not hear the compressor cycling, or even kicking on. I know what it should sound like and that the idle should go up a bit when it cycles on, and down a bit when it cycles off, and nothing is
happening. I looked at the manual and the fuse cover under the hood and do not see an "A/C" specific fuse. Does anyone know if there is a compressor fuse or if it is tied to one of the other fuses. The blower fan works fine at all positions, but blows out hot air. Oh yeh, by the way, I have the manual A/C not the auto temp variety. I see the A/C relay in the under the hood fuse box, but no fuse. Could it be that the relay is fried??? I'm thinking that the compressor HAS to have a fuse in

Use a different relay from the block and plug it into the ac spot. See if that works. And it should kick on with low refrigerant. My wife's car, the relay was slightly misaligned causing it to sometimes work and sometimes not. I'd start with the relay. Joined Oct 5, 2012 · 21 Posts
You need to check the level of your refrigerant if its to low or even to high it won't kick on at least that's how mine was were I live its about a $70 service to get all that checked. Good luck! Hope that helps Sent from my SAMSUNG-SGH-I717 using AutoGuide.Com Free App

see if the wires are secure in the clips and plugged all the way in. after years of vibrations mine came apart. Will that switch also affect if the fan comes on at all? My A/C is still cold, but the fans aren't blowing at all. I replaced my cabin air filter a few months ago, and there is no noise, so I figure it's an electrical issue. It's happened before where it wouldn't turn on for about a day, then the next day it's fine for months. Thanks Joined Sep 2, 2012 · 2,660 Posts

see if the wires are secure in the clips and plugged all the way in. after years of vibrations mine came apart. Based upon all that has been said; get a Test light OR a DMM. Unplug the connector in this picture and turn on the AC. If the lamp lights and/or you get battery voltage i.e. 12+Volts from the plug to ground, everything from the switch through the fuse panel is likely OK. The exception is if the pump/AC compressor is low on refrigerant the low limit switch will keep the compressor off. The refridgerant in system circulates the oil to the pump. If its low, the oil won't make it to the pump and it'll burn up. A hand held meter is worth every penny. Start there, but yes, there is a relay and a fuse. Make sure they are in place and working.

The easiest way to force the AC clutch to engage is to bypass the relay. A paperclip will work just nicely! What are the static pressures on the high and low side of ur AC? Tomi Joined Sep 2, 2012 · 2,660 Posts

Anyone get anything figured out? I recently discovered that my compressor is not kicking on. The relay is fine, and I want to check the power going to the compressor, but I don't see the same wiring harness that flipper posted a picture of on my 2007 6i. anyone know where it is located on a 2007? from all the reading I've done, It seems to

Mine turned out to be no refrigerant left. The o-ring by the fitting at the compressor was not sealing properly. I found that out by using one of the r-134a canisters with the gauge attached which also comes with green sealant to supposedly seal any leaks. The green stuff was leaking out the lower fitting. Got another o-ring from the dealer and was good
to go. Joined Dec 26, 2006 · 581 Posts
Mine ended up being the AC control head.. The signal from the pcb up by the radio wasnt sending proper signal to turn on the compressor. I found a whole used head unit out of a totaled car on ebay for $95 shipped and swapped my custom radio stuff onto it and it worked! Thank god it wasnt too bad..
