Air conditioner not working?

Our 98 T & C had the same problem. While we had it at our local mechanic for a seperate issue they fixed the blinking light problem as well. They said Chrysler told them what to do to stop the blinking lights. I am not sure what was done but I can try to find out for you. In the meantime check the TSB's (Technical Service Bulletins) or call Chrysler corporate customer service. I'm pretty sure it's a quick fix because they didn't even charge us to do it but you will probably need an OBD II scanner to fix it but again, not sure. Good Luck

A/C not blowing cool air, somewhat warm but not hot. Mechanic topped off freon and still same. A/C will not turn on immediately upon starting either. Two lights are flashing relating to the wipers, there are 3 lined up vertically and the top two are the ones flashing approximately 5 minutes after starting before they stop. Not sure if this is related. Possible relay problem?

Also, read on another post with similar problem on a clunk sound when driving slow over a bump, 5-15mph, on the front end. Any solution to this assuming its a common problem with this vehicle. Submitter had mentioned something about a possible control arm bushing.

Pressure switch could be bad for the AC, I have seen this before. EASY to replace.

I'm willing to bet it is your sway bar bushings where they are bolted to the crossmember, these are always the culprit in chrysler minivans.

As far as the clunk goes, my 96 did the same thing and it was the sway arm bushings that I had to have replaced. Now no more clunk.

The clutch is not engaging. Disconnected the clip which seems to go to the compressor and checked with volt meter and there is no voltage present. I measured the resistance of the coil and found a value, so I connected a cable with a fuse and fed 12 VDC and the clutch worked and I had cold air for a few minutes, until I observed that the fan was not working and I chose to disconnect the cable for fear that the pressure would increase. What could be happening? I checked the clutch fuse (15 Amp) and the clutch relay (with external 12 VDC) and they are okay. What condition is missing for the clutch to work, just by turning on the cold air button? Thank you

Thanks for your answer. I have 12VDC at the base of the relay, I checked between them and with respect to the negative of the battery. The weird thing is that when I connect the relay, I don't feel/hear the coil activate, like when I feel it when I testing it with an external 12VDC source (I also externally tested the state change from NO to NC). Is it possible to "lose" the voltage when connecting this 78 ohm resistor relay? Another question, shouldn't the fan work, as soon as I press down the cold air button? I replaced the relay with a new one and the same thing happens. The coil is not activated.
Thank you

In the photo that is blocked with my hand, I am measuring the upper terminal of the relay base. Thank you

I checked voltage with respect to two different body ground and the result is the same. I checked for resistance at a point that I believed there would be continuity. Thanks for the support.

I have a 1996 Chrysler Town & Country 3.8 LXI with 138,000 mile. The AC blows warm to hot air all the time. Do I need to recharge it or is it another problem. My belt runs fine and doesn't wear abnormally so I don't think it is the AC pump. If it does need a recharge which one do I need to get and how do I do it safely?

Okay, I did that test yesterday, but I was not very specific when I explained it in my first story; the compressor works, but it exceeded the pressure (I think I add extra of gas in it) and a green liquid came out of the head (maybe the previous owner added it to detect leaks), that's why I stopped the compressor. Replace a couple of o'rings and I left it ready to be able to detect why it does not activate automatically. In the last voltage measurement I made, I felt that the relay coil was already activated. I insist should they turn on the fans when I turn on the cold air conditioning?

Thank you for all of your help.

Okay, just yesterday with the help of a friend who has the equipment, we evacuated and added enough again; When the over pressure happened, it was the only time I saw the fans turn on. My problem is that the cold air conditioning does work not automatically. In your skill what other factors could prevent this from being achieved? Why automatically the voltage does not come to energize the A/C clutch?

Thanks again
