Help with A/C. (Video)

[239]

I posted a thread about this a while ago. Whenever I turn my A/C on my RPM rises and drops, there's also a clicking sound that it makes while it does this. Here's a link to the video. Sorry about the low volume.

The clicking sound is the compressor cycling.
RPM's get a slight boost to compensate for the load when the compressor is engaged.

Is there something wrong with your A/C? Is it cooling correctly?

The air comes out cool, not exactly cold, even on the lowest setting. My friend looked at the compressor and saw that it turns on/off while the A/C is on. He said that the compressor should stay on as long as the A/C is running. My compressor's the stock one from 2000.

The compressor cycles to maintain the correct line pressures and evaporator temperature, it's normal. If your a/c isn't ice cold, have the system looked at by a qualified a/c tech. It's possible you may be a little low on R134. An evacuation and recharge may be necessary to bring the system back to full strength.

The R134 was replaced just a few months ago as part of a tune up my mechanic did. I don't want to judge the compressor just by appearance but it's pretty old with some rust on it. I've got a new one that's been sitting in my room for a few months now. Not sure if I should replace it though, but I'll have someone qualified look at it.

You have a check engine light. Have the codes read and search them.
