2004 Acura TSX AC Issue (Video)
Can't get into the dealer until Friday morning and trying to prepare myself for what might (or might not) be coming.
AC went from cold to hot air while driving at about 35 MPH after it had been blowing cold for 10 minutes. Didn't hear anything "blow up" so I am hopeful I don't have the known issue where you have to replace the entire system.
I had the relay replaced last year when I had this issue and the AC started working normal again. I've been reading other possible issues on the forum and perhaps there could be something with the voltage for the clutch coil?
The video shows what's going on under the hood at a high level. First with the AC off and then attempting to engage it at Lo/Max. You'll hear that the fan turns on and it seems to want to engage, but hot air.
At this point just trying to determine how severe or minor it may be ahead of getting into the dealer Friday. If it is the entire system I have to be ready to decide on the fate of the car. 11.5 years and 141,000 miles so far.

Impossible to tell from video if ac compressor is engaging (clutch end plate turning). First step is to determine which is the case (engaged or stopped).
If stopped, check whether 12V getting to the clutch coil (single blu/red wire connecting to compressor). Backprobe w/ pin to allow VOM voltage measurement.
Post what you find.
If you're only looking for possible quick fix, replace the ac compressor relay. It is a frequent source of no compressor engagement and is cheap (<$10).
good luck
