It usually happens after the battery runs down or is removed/replaced. If you have someone turn the fan on and press the a/c button while its running while you look under the hood you can look at the compressor pulley and if the middle of the pulley stays stationary and doesn't click and start spinning with the clutch it could be a bad clutch or more likely just low on r-134a
First of all, since it's the winter season, it may be too cold where you live for the second procedure to fix the lights. It's called the cool down test and it determines how long it takes for the evaporator to drop 20 degrees once the compressor is engaged. Your A/C must also function properly for it to pass the test and the lights to stop flashing. It should be around 60* F for the test to be done. So this spring would be your best bet.
Very helpful video, the problem I have is, the recirculate button light never does come on when pushed, either in test or normal mode, air flow does not change either, bad control board? any advice? Thanks.
The procedure is to Turn the blower speed to high, move it to the full face position, be sure all the a/c vents are opened, set the temp or temp sliders all the way to cold. Press the Rear windshield wash and A/C button's together for 5 seconds. It will perform a series of flashes or the like (it's been awhile) and once it's finished the lights should go out. If not then it has failed the cooldown test and that means that the a/c isn't functioning or isn't functioning to its fullest extent.
How long should you wait when you do the test on the first and third button it seems like I waiting a long time and the first two buttons just flash. MY issue is my heat was working and then all of a sudden just isnt working now that I need it some mornings.
Actually yes the weather is still very cold here so that may have something to do with it. However my van died and this is when this started up. I wonder if my a/c clutch is shot and its possibly throwing things off.
The last two buttons on mine (circulation and a/c) keep on flashing when I push the first one(rear wiper) at the end of the process like you did... How do I fix this?
Goodevening sir Thank you for your video about chrysler hvac calibration But i have the same problem the aircondition light and the switch beside it is flashing all the time, I did what you show, but dosn't work Please Can you help me My car is dodge caravan from 1998 3,8 AWD Best regards from me jamal from Denmark
@sideburns2009 Just like the other guy who wrote here, I now only have two flashing lights, and as you wrote, it's failed the cool down test on a cold day. Is the only thing I can do is to wait for the weather to warm up and then do something again? ...and would that be to press the wiper and spray buttons and that is the start-up for the test? Thanks!
All 5 of my lights are flashing.I tried this but my circulation and a/c lights flash twice then rear wiper flashes once and this dont stop. whats another option to fix it?
When my nieces van goes through the test the ac and recirc. lights blink also. Then when test is done just those two flash together. Whats up with that. Test did make other two quit blinking. Thanks!
I have an 01 Dodge Grand Caravan 3.3 liter my heater control AC panel is not working due to resetting the computer when I took off the plug wire please help me
If the a/c and recirc lights remain flashing then it failed the cool down test, if they go out then it passed. If the rear wiper wash and rear intermittent (the one with the dotted line) wiper lights still flash then it failed the calibration test and you should repeat the procedure in the video.
Most annoying issue ever. It's too hot outside to run the cooldown test properly so I'm stuck with these stupid frigging flashing lights and there's nothing wrong with the system. The battery died and it's blinking off now.
Could be too cool outside for the cooldown test to work. It has to sense a 20 degree drop with A/C on. If it's already cool out, it can't drop it 20 degrees so it fails. A warm garage is needed if it's cool out.
Thank you it was very helpful I took it to a mechanic and they didn't fix it so you were a big home
Thank you. Very short and to the point.
Problem solved. This rocked, thanks for taking the time to upload this video.
UTube FORCED NAME no problem

There is also a second procedure to run the cooldown test which are the lights that are probably still blinking if this doesnt fix it.

If it fails the cooldown test, what I did was put the heater for like 2 minutes then I tried again and it passed
My a/c controls on my 1999 Dodge Custom Van will not switch properly from one setting to another
AWSOME THANK YOU PROBLEM SOLVE

@@sideburns2009
What SPECIFIC buttons did you push?

Hey thanks.
It started with my battery being too loose.
I thought I activated the self destruct system ;-)

Why don't get the reset?
