I've got a 00 RX300. The light on the AC button flashes and intermittent cold. So I figured it was the relay. Inserting a paper clip, I know it's a no-no, keeps the air blowing. So I moved another of the exact same relays over to the AC slot (see picture #1). Still no air. So it doesn't appear that another relay fixes it. But why would the paperclip get it running? The problem with the clip is that it quits after an hour and won't blow cold again for an hour or so.
No matter what combination of relay moving between 1,2, and 3. The air will not blow cold without a paper clip.
1) is the AC
3) is fuel pump

I have a 2007 ES350 with 92,000 miles the past few months when I start her up and the thermostat is on high fine ash like particles come thru the front vents. Its heavy at
first, then after a few seconds it tampers off. I have changed the cabin air filter, what could it be. This is a good car no problems except that. Please help
