2003 Honda Odyssey AC problem

AC used to stop blowing cold air a couple of minutes after the car was in idling or very slow speed. But once the speed was up, then it started to work perfectly.
When I was doing the oil change at Jiffy Lube last weekend, I told them the problem (it's been like that for a couple of years and I did bother to get it fixed) and they said it could be due to low freon. So they added a couple of cans. The day was pretty cool and I could not test it.


However, the AC worked intermittently after that. I took the van back to the shop and was told that the compressor was not working and it could be due to low pressure (leak somewhere). It appears the compressor could kick on for a few minutes, then it would stop. I then turn the AC off for 5-10 minutes and the compressor would work again (regardless whether the speed is up or not).

Now I find that if I turn the rear control to off, then the AC works just fine. When I turn on the rear AC, then the compressor would stop working.


Any suggestions?


Thanks a lot!

I'd suggest taking it to a Honda dealer having a qualified service department. There could be an electrical gremlin that their service diagnostics can detect in short order. Never heard of such happening, but they would be in more of a position to know. We have a 2010 Odyssey (named him Oscar), and just love the thing.

Jiffy Lube servicing AC?

points towards loose belt

So they added a couple of cans.

points towards system being overcharged; when compressor builds up pressure, safety kicks in and shuts off AC.

Have no idea on rear controls.

i would make sure both fans in the engine compartment work when compressor is on. with both rear and front a/c on it has a heavy load on it, increasing speed of van help cool the condenser like the fans should do at idle. But like said before the system should be checked by more qualified people(and warn them of the cans used to fill before, they have stop-leak in them and WILL damage an A/C machine) to get a proper charge on the system. they are also very bad about relays going bad. they are labeled MG CLT in the fuse box under the hood.

Thanks a lot for your suggestions! I'll take it to an AC specialist or a dealer.

Super Walmart has good price on AC jobs. Sniffing leak, evacuation and recharge. Used to be $120.
But first and must thing to do is to sniff for leaks, otherwise - it's a total waste. 2nd thing - check on pressure.

Our Super WM doesn't do A/C...just tires and oil. And I don't think that's such a great price. Local shop did same with valve core replacements for $118. Might be more in your area I guess?

Lesson is...always shop around.
