AC problems

When I turn my ac on the clutch will engage for a few seconds then it stops for about 30 seconds and does this over and over. Tried to put freon in but it would not take any? Any ideas?

What was the ambient temp?
It is supposed to cycle when all the conditions it is trying to meet, are met. Otherwise it'd blow something up.

It was hot outside and it was blowing hot air like it was stuck on heat. I would guess probly about 80 that day. I could here the clutch kick in and out. Would not stay engaged just in and out blowing hot air.

In that case, you may need your air gap changed. There is a gap between the clutches. Mine would do what yours did, just cycle. It's cause it would engage but never actually get close enough to pump, so it shut it off, and started over for safety.
Mine was re-gapped in 07 or something and that's the only time I've had to have it done.

Would that be the bolt on the front of the clutch? Take it out and use a smaller shim? Can that be done without removing the belt? Thanks

Just found an old thread about checking the low pressure switch and taking the shim out. This is a great place to learn and helpful people too. Thanks Jesilvas

Could you post that thread? I need to know how to if I ever do it myself
And removing the belt isn't hard. Might as well take a minute and just do it.

Here it is. The temp has dropped to the 60's today so I don't know if it did any good on removing the shims or washers, that is what they were. AC Problems!!!!!! I did a search on ac problems and it showed up.

Pretty common. I've never really heard of the system going bad, just the compressor wearing out.
