Hey,

I was using my Air Conditioner in the Parking lot..I turned it on to setting one, You can feel the A/C unit vibrate alot...It seems to be fine, then the next minute vibrate alot and make a noise, then the next minute vibrate....this goes on and off....Is this suppose to happen? Or is my a/c unit going bad? I havnt tried it while driving around yet ...

 

I noticed with mine that if I have the recirculate option activated, it vibrates. But, when I don't have that on, it doesn't seem to make any noise. I am pretty sure that it didn't always act that way, so I would be interested in finding out what the cause might be. Maybe just a flap not closing all that way due to age?

 

thanks ill give that a try today...

heh im not to familar with ac's...

 

Also if you have the Fan setting low with the A/C on you might feel the compressor cycling.

 

YES its on low when the vibrations happen, but is it supppose to happen that often?Like every 20 seconds?

 

The compressor cycles from Low pressure/Cold temp.
They are designed to do this to prevent the Evaperator from Freezing.
Turn the Fan speed up to about 1/2 and it will take longer to cycle.
