Defrost a/c fan engagement question
2003 DX 4-cylinder. 35,000 miles.
1.) I had to put refrigerant in a few weeks ago when I tried the a/c for the first time and realized it wasn't very cold (It's hard to make sure the a/c blows cold when you buy your car in the beginning of February!). A/C now blows reasonably cold.
2.) I've noticed that when A/C is on, or defroster, the fan kicks in, but it seems quick. It's about 7-10 seconds of fan, followed by 20-25 seconds off. 7-10 on, 20-25 off. I realize the A/C and defroster both operate in conjuction with the a/c compressor.
My question: Is this normal cycling? If not, is there anyone who has experienced this? Fixes?

If your A/C is a little cold then you might not have put in enough refrigerant. Its pretty hard to put in the right amount of refrigerant if you don't have a recovery/recycle machine or a vacuum pump and a scale. The A/C is suppose to cycle on and off b/c when the A/C gets too cold the A/C has to shut off so the refrigerant lines don't freeze. I don't know why your defroster keeps shutting off.

I have a 2005 accord and am experiencing the same on/off cycles you are with your ac/defrost selection. When your fan kicks in... do your headlights dim for a split second??? Mine do and its really getting to me. Every 30 seconds to a minuite the ac fans kick on which caused the headlights to dim. Very very annoying.

RE: Defrost a/c fan engagement question
my fan cycles on and off with the compressor on my 98 and stays on contantly with my 94. I would guess that this is normal for the 1998+ cars in order to save drag on the engine?
