AC Hissing on 06 EX EB 4.0 2wd

[Lee29720]

I have an 06 EX EB 4.0 2wd with 25k miles. I took it in for some other warranty work and I reported a hissing sound when the AC is turned on. The noise sounds like a pressure release, but is repetitive. It kind of sounds like a pressure cooker. It comes from the PS under the glove box.

The dealer, of course, could not duplicate or repeat the noise. I can't pinpoint the location myself.

Any thoughts? It is only when the AC is on and more pronounced on #1 fan setting.

there is a tsb regarding this issue, it has to do with a little pin hole when the conector hooks to the fan motor housing
