AC Problems

[the bandit]

Im wondering why my AC is starting to act funny. It will blow nice and cold on all levels but then sometimes it wont blow hard even if its on the top level. When that happens their is usually water or dripage that comes out on the passenger side inside floor dash. When it doesnt blow full blast out of the vents I still hear it blowing but the air doesnt come out as fast. And no its not coming out of the top defrost vents. If I turn it off and leave it off for a bout 5 minutes it will resume and fix itself. Thanks for your help.

if you have a vacuum problem then the mode door will default to the defrost vents and not the dash vents. Is that whats happening?

[the bandit]

No I dont think so....is their a way I could check my hoses? I dunno Im stumped.

you say that sometime sit blows from somewhere else or is it that it's just not blowing strong enough and blowing in the same place? can you explain this better?

but then once you leave it off for a little while it's better? is that what you mean?

What could be the problem is that you may have a blockage in your drain pan from your evaporator which is making the leakage go to your passenger floor. What you can do is get a screwdriver and poke the plug so you can free up the material which is clogged up in your drain.

Well the AC will blow regularly unless I run it for an extensive amount of time. Once I have run it for aover about 45 minutes I feel a decrease in the amount of air coming out of the vents. This is noticed at all levels of the Ac blower. When I turn it onto full blast I can hear the air beeing pushed out but it isnt coming out of the vents it seems to be blowing but not coming out of anywhere. At this time I usually notice a leak on the passenger side near the front center of the dash. Thanks

you know what it could be?


3 things come to mind.

1The blower motor could be drawing too much power form it being burnt out.

2, the evap drian is pluged and water is backing up and causing a lack of flow

3 you have a pressure issue and the evap core is freezing up and not letting air through

I vote for #3, the evaporator is freezing up. Then after it sits and thaws for awhile it works OK again. Check to see if you're low on refrigerant. You can get a guage with the refill kit at WalMart, Target, etc, they're cheap and easy to use.
