HVAC - Does anyone know where this is?

[RoushTang11]

I saw on another thread that someone was having HVAC issues similar to me. They bought an Air conditioner pressure transducer (part# mt3500) which solved their issue. I know, I know. I shouldn't just throw parts at it - but I figured it was cheap enough to try. However, I can't find where it goes... I'm not seeing a dryer canister which is where I thought it might be... Any help would be great appreciated!

I have a 2011 Mustang GT 5.0L Roush edition, if that helps.

Might be high pressure compressor shutoff switch? A transducer transfers mechanical function to electrical or vice-verse. How I always defined anyway.

I found out the real part number is "HG1Z-19D594-A" - can anyone tell me where this is located on a 2011 GT?

This might be the location? Googled part number and schematic...

It's the AC compressor cycling switch so you should find it on the low pressure side near the dryer/accumulator. On the 05-09 GT it's by the firewall in the driver's side corner next to the clutch/brake fluid reservoir. I know yours is an '11 but that's the first place to look.

11&up does not use a low pressure cycling switch.
The high pressure transducer is on the compressor discharge line.

I saw a couple of those diagrams - but didn't really help. And I'm honestly not this dense!

So maybe leading away from the actual compressor itself?

Just trying to help buddy... that's what the forum is for.

Yes, not maybe.

Don't get me wrong - I appreciate the input. I'm just saying that - I couldn't make heads or tails of the diagram as to where on the actual car to look!

Yes, not maybe.

Thanks! I'll see if I can get under later today if the rain stops!
