Unusual, Very odd, Odyssey Air Cond issue
I have a 2007 Odyssey - took front clip off and installed the Blue Ox base plate - while installing the darned thing I slipped and put a crease in the fin of the condenser ---- checked the crease with bubbly spray and yes - it was barely seeping. So --- ordered a new condenser and "O" rings and replaced it.
No huge problem - slight issue with ego is all.
I checked the freon 134a and found the necessary amount to put back in the system - so I added a few drops of AC oil (yes, it was correct oil), and then put in the freon.
As I was adding freon the system begin to work like a champ --- great, I thought - problem NONE. I actually added just barely too much freon and went over the 45 mark - so I bled off a couple and got it back to the proper range.
Few days later wife and I drove the van to Davenport and little south - well over a 500 mile round trip for us. The system worked great just as before and front and rear AC outlets pumping out that nice cool air. Temps were just on the mark.
Friday -- hooked up and towed the van up to Mystic lake. On arrival I started van up and put in park so unhook her, the AC was blowing hot air------.
When I got finished unhooking and the errands setting up I grabbed my gauges and found my pressure was just over 100.
How in the dickens did it get up there??????? I didn't put it in, no one else has access to -----
I thought about the issue for a few hours and then the next day (Sat) I decided to bleed the system back down to 25 and then re-add new freon and just see what happens.
Once I bled it down below the 40 mark the system started working like a champ again -----------------!!!!!!!!!!
I took it on down to the 25 level and re-added new to bring it up to 39 and monitored it for a while. It remained there....
For you AC experts out there ---- fill me in on what just happened, please!!!!
I have probably worked on 4 or 500 vehicles like this and never had that problem before ---
I have a theory ---- little illogical, but it is a theory. But really, I am baffled on this one.
Yes - it worked the rest of the weekend, working now and all is good.
