Hello, I'm new to the forum, and to the world of DIY car stuff...

My RX330's A/C started cooling intermittently. The local mechanic, after trying a recharge and leak check concluded that the next likely cause is the pressure sensor.

I found and performed the diagnostic procedure, and got code 24 = pressure sensor, which seems to support his diagnosis.

He said he could only order a whole assembly containing the sensor from the dealership, with a steep price tag, and that I was welcome to try to find it on the internet myself, for less, and he would install it.

Who is good at the part number game?
The assembly (matching the 2005 RX330) seems to be 88710-0E011... and that seems to include the pressure switch?

The pressure switch by itself is 88719A... but it doesn't seem to be available at all for the 2005, only for other model years.
Any chance I could find it somewhere? Or that the 2006 part (88719-40020) still fits the 2005, even though all the part websites say its not a fit?

Thanks!!

And to make it more confusing...
I just realized that the assembly: 88710-0E011 is listed as compatible with both the 2005 and the 2006 model on the parts websites.
So why would the pressure switch that is included in the assembly be different and incompatible between the two years?

Assembly pic part number may be obsolete and replaced with another, pretty typical actually. I think this switch in the link below is the one you need, however call this company (they're a ClubLexus vendor) to check, as it doesn't specify exact model, which is odd. But it seems to be a standard pressure switch used in many Lexus AC systems. Again, call to confirm first.
