'99 EB - I tried swapping the express down relay (#4) but it made no difference. It doesn't auto-down until it's halfway down after pressing it four times. Does anyone know if it can be recalibrated or reset?
Ambient: 88F
Static: 105/105
Active: 55/200
Looks like it might be a little low, chart says it should be more like about 225-250.
I went ahead and fixed the blend door so my main A/C works again, and it's blowing cold... but could be better. I'll charge it a bit more and get the high side up...
I've got the separate controls (on the ceiling) for the 2nd row that I'm setting to HI and COLD and have the ceiling vents reversed to point forward. The front still blows across the heater core because of the broken blend door, but it's blowing it on LO into closed front vent doors so it's not...

So normally when your A/C blows warm when you're stopped, it's because that A/C booster fan isn't working. So what if you don't have one?
My rear/overhead A/C is all I've got at this point thanks to a failed blend door. If I put it on MAX A/C, turn the EATC speed to LO, and...
I was charging the A/C in the Expy yesterday and suddenly the key fobs all stopped working. I had just programmed 4 of them the day before. It won't go into programming mode, and the code on the door doesn't work either. I tried pulling the battery negative cable for 15 minutes or so, but it...
Yes, and I was right that it was a PCM problem and not a fuel problem. Stamp was right about Fuse 30 but I checked it, rechecked it, and tested it and could find nothing wrong with it, didn't know what else to do. Last thing I wanted to have to do was to have it towed to the dealer and pay...
I told them the whole story and said bottom line was, I knew that the PCM relay circuit was dead and I didn't know why. Bedrck47 you'll be very disappointed to learn that it was the #30 circuit, the fuse terminals were loose and not making good contact. They said after that it fired right up...
Thanks guys, and happy new year!
No work had been done on the fuse block prior to my problems, this all happened suddenly.
It's cold, dark and raining or snowing here most of the time this time of year, so I don't have many favorable opportunities to go up there and check things out...
