2000 Plymouth Voyager AC Blowing Hot Air) Sign In

First off, I don't even qualify as a back yard mechanic. I am more of a too broke to take it to the shop so I am hoping it is an easy fix kind of guy.

Here is the info that is requested in the tips:

2000 Plymouth Voyager
3.3 L
about 94000 miles

The air conditioner suddenly started blowing hot air at the end of last summer. It didn't happen slowly over a period of time. To me it seemed like one day it was blowing ice cold air, the next it was blowing hot air. When I press the air button, I do not hear the "clunk" that I used to hear which I believe was the AC clutch engaging. I do hear a noise when I push the button for recycled air.

So far, the only thing I have tried is to switch out the AC clutch relay with another relay in from the box but nothing changed.

I think it is possible that is leaking freon because it was leaking liquid last fall which I thought was just condensation but my wife insisted that it smelled like antifreeze. If that is the case, would I hear the condenser kicking on or does it just give up if it is empty?.

Is it worth trying to fix it myself with a can of stop leak or should I bite the bullet and take it to my mechanic (who is awesome but he won't take pocket lint as payment).

I'm afraid that you either need to learn to live without A/C or save some money up because this problem is going to be well beyond anything you are equipped to deal with. You can also do a lot of damage trying.

Please don't use stop leak as it could make a real fix a nightmare and those kits with hoses you see are not accurate and only tell a low side #. Worse - they usally fail.

#1 reason for poor or no cooling is low charge from a leak. Look for oily spots on parts and hoses especially front of compressor and perhaps condenser caught a rock - some aren't so expensive.

This is a trade to itself and a lousy DIY thing but you could get lucky and find the leak by evidence then get help as it takes equipment to do this right AND a lot of know how just to charge a fixed system.

Read top post in this section of Charging procedures. Should impress you on what it takes.

Perhaps get a pro A/C to give it a quick look to know if this is an expensive fix or not,

Thanks guys for the info. The forum emails were directed to my spam email so I didn't think anyone had replied.

I put it off long enough. Temps have been in the 90s and my kids and I are going on a pretty long trip this weekend so I am going to take it in.

The good news is that I have a really good mechanic so if I take it to him, he will give me the best price on fixing it or give me the info I need to fix it myself if it is something simple. There is no substitute for a mechanic you trust.

By the way, I did attempt the home charging kit before I read the above post and you are right, it was useless. Actually, the little meter said that it was already filled so who knows. I don't know much about auto repair but I know enough to sense when I can make things worse by messing around too much.

I am really hoping it is something simple.

We usually get to posts the same day or just hours!

Just set you computer to accept this site which trust me is NOT spam or collecting data on you all.


Actually glad to hear you have a trusted tech as this can be a pill to learn and do right. It can be expensive to DIY this stuff and real expensive if you screw it up.

Good luck with the fix,

Tom
