Automatic Climate Coltrol

Odd question, but my CX-5 touring came with manual climate control. I was poking around at a local junkyard and came across a CX-5 with the automatic climate control that comes on the GT models and may have been an option on the Touring. Does anyone know if I could connect this to my car and have it work correctly?
 
I imagine what you are asking is doable but it's probably pretty involved.

I wouldn't bother, most auto-climate controls are not much easier to use than the manual one you already have.

If I feel too warm, I turn the little red/blue knob down. Too cold? Turn it up.

Easy.
 
gv There is quite a bit to it as the air mix door for each side has to be controlled by the panel. I think you have only one air mix door that is mechanically attached to the knob. Old designs had vacuum motors on the air mix doors but they may have electric stepping motors now. The fan motor is also controlled but that is likely in the panel. There has to be a thermostats in each side and probably a sun compensate thermostat on the dash. Auto air is not an option on the touring. You could look at the service manuals that were posted and see how many components would have to be changed out.
 
hmm wish I had a local junkyard with a cx-5. I want an extra exhaust manifold for possible modding also just found out the mirage is standard with auto climate control..

Easy.

Not so easy if the person next to you is cold, and you are hot.

True, I forgot about that difference.

The auto climate control probably requires different heater/ac ducting manifold then. Meaning not an easy swap.

I have auto climate control on my Volvo S80 and just remembered the (slight) inconvenience of turning two temperature controls when I want to change the temperature. But the Volvo has heated seats so if one person is too cold, they can just turn on the seat heat.

On CX-5, only one control (driver's) needs to be changed to change the temp on both sides UNLESS the passenger side control is "taken over" (i.e., set) by the passenger. Pretty convenient set up.

I bought my CX-5 with manual climate control because of the experience with my last car, an '04 Subaru. That car had single zone automatic climate control. When you started the car cold, once warmed up the fan would spool up to the highest speed, and you manually had to adjust the fan speed or wait for it to self-adjust, which always took too long.

The one feature I do miss on my Mazda is bun warmers (heated seats). They always seemed to help compensate for a sluggish cabin heater on cold Maine mornings.
 
I totally miss my heated seats. My middle road ford focus had heated seats and they spoiled me. Luckily I had that car during the winter of polar vorteces, so I survived.
 
I find the dual climate control a waste of time, first thing I do is turn off the aircon which it defaults to on start up.
All I do is make sure the aircon runs for a while every so often to keep the seals lubricated.
 
it would be a huge amount of work to swap over. Consider that most manual HVAC controls are cable driven (as in a manual cable moves and controls the flaps to achieve the desired settings) Automatic climate controls use a completely different air handler which has electronic actuators that move the flaps. Add in dual zone climate control and it complicates matters even further.

Additionally, the car's wiring harness would more than likely be different between the two and different fuses and relays would need to be added.

As for you heated seat guys . . . you can add aftermarket heated seat pads to just about any vehicle. (we install them at work quite often) Roadwire makes a reliable kit: http://roadwire.com/s.nl/it.A/id.168701/.f The price listed on their site is about what we would charge for both front seats installed parts and labor.
 
Pretty sure most (if not all) cars use electric servos for the flap actuators nowadays. The CX-5 does certainly, even for the manual (see the schematics).
 
Do they still use cables in some cars? I thought basic was manual pneumatic actuation at this point. My '96 Explorer is completely pneumatic on manual controls but there might be an electro-mechanical on the temp door in HVAC system.

On a side OT note....anyone know if Mercedes still use pneumatic actuators for their door locks?

Mercedes began phasing that tech out in the early 2000's. All of their modern cars use standard electrics now. Well as standard as data driven electrical components can be.

If that is the case on the base climate for the mazda, it might not be as difficult to swap.

BTW, plenty of cars still use cables. Usually on any of the entry level vehicles to cut cost. Especially if the car doesn't have an upgraded option for automatic climate control. Just from recent experience: Toyota, Scion, Hyundai, Kia, and Nissan still use cables. Usually on their sub $18k vehicles.
