When I switch the compressor on it goes to my suggested pressure and then stops which is what it normally does but then it kicks back in again 1-2 secs later but continues to cycle on a "low rumble".

Your system might be low on freon. Get a kit with a hose that has a gauge on it so you can see if you are in the "Good" range. The cycling switch won't close unless there is enough freon in the system. You can temorarily jumper the connector for the cycling switch to see if the compressor will come on. If it does, you are low on freon for sure. Do not let the compressor run for more than 15 - 30 seconds with it jumpered.
report back results.

Hello maddaddy23...if the low pressure switch on your villager is not stuck open, check the compressor clutch coil it could be open (shorted or loose), Check the climatic control switch... and last but not least make sure compressor operation has not been interrupted by ECM...
Good luck...i hope this helps

It could be your low pressure cycle switch is going bad. Check the connection to the switch and it's is located on the A/C Accumulator. The other thing to check is the A/C relay and that is located in the glove box. There is a panel in the glove box that say's relay, there is three relays in there and one of the out side relay's out of the three is the A/C. can not remember which one it is. The middle relay is the fuel pump and the other one is the third break light. Switch the two out side relays and see if your A/C get's better. the other thing too is if the R134a is just a little low, and needs to be topped off. Good luck and hope this helps. if your going to try to recharge the A/C system your self, keep in mind not to over charge.

dont get a rebuild compressor they never work very well it sounds like the a/c has a restriction the only way to tell is to pull the orfice tube or expansion valve to find out the compressor will push metal into it if the insides of the compressor if failing

Check the high side ac clutch cut out switch,witch could be in back of compressor,or in a high side line.By pass the switch to see if the compressor will come on.Also the ac module could be gone out.First check the ac clutch relay,or better yet swap it out with a relay just like it,same number will be on the relay,this will tell you if it is the relay.
