I purchased a TYC after reading the reviews on the different manufacturers it seemed pretty good.

Similar problem for the last 2 years on mine. Blows hot air for about 10 minutes, then instantly icy cold. One major difference though - I have no aux fan on mine. 2005 4.4, and it did not come with the aux fan. Apparently some did and some didn't. No clue why, or why it won't blow cold until it feels like it. Other posts on this have revealed nothing except that I'm not the only one with the problem.

I agree with upallnight, you can't start a thread called "hot wife" and not post a pic!

No pics
No help

[Beamernewbie]

You guys are brutal with the pics! Lol

I have the same problem on my 2002 3.0. The ac hasn't been blowing cold until i start moving. It's not consistent though and sometimes will work while others not.

Remove the hvac control unit from the dash, take it apart to where you can clean the junk stuck on the temp sensing wire, you'll know it when you see it. Just like the element in a MAF, these can get nasty. See if that helps. Clean the dust off the little fan too while your in there.

So I removed the unit and sensor wasn't dirty all and actually looked like new, however it was out of the hole where it is supposed to be located and just kinda hanging behind the hvac controller. I put it back in and it did not make a difference. I had seen a utube video where a guy was experiencing a similar problem on his bmw and he revved the engine to about 4k rpm and it started cooling. He never said what the fix was however. I decided to do the same and it instantly started to cool. Any Ideas?? Thanks

Sorry, didn't read the rest of the thread. Could the clutch on the compressor be failing? If the revving influenced it, maybe it's not engaging correctly?

I'm having the same issue, aux fan will not engage when the AC is on. I'll have to try that trick disconnecting the pressure switch to test the fan
