2003 Honda Pilot a/c compressor stopping after 2 secs.
My 2003 Pilot is doing the exact same thing. Compressor comes on for 2 secs then shuts off. Warm air will blow out of the back but nothing coming from the front. Ugh!
If I leave the vehicle running after the compressor has shut off (2 secs), and
then switch the air off and back on again, the compressor will not come on. However, If I turn the car off and then back on again, the compressor will come on for 2 secs and shut down. Baffling - I know. Several different shops have looked at it and scratched their heads only to tell me they have no idea what's going on.
I've dropped it off at Honda this evening to see what's going on. Unfortunately my extended warranty just ran out so I hope this won't set me back to much - I'm suspicious it will. A/C problems are never inexpensive. In the meantime, I'm going to research and see if this is the same compressor that is on the CRV. I've heard of major issues quite similar to this on the 03' CRV.
I'll let you know after Honda has had the opportunity to look at it tomorrow. Good luck!

The first thing to check when compressor cycles on and off very often is low froen gas, a compressor is going to cycle off and on but you should have cold air if it is running correctly, it will turn on and run for a while ,like 1to 2 min, then shut off for a few sec, then restart, if yours is going off and on fast and no cold air then have the gas checked first
on the evaporator (silver canister looking thing) is a 2 wire plug (pressure switch) pull these and put a jumper wire between them and the compressor will start, if it doesnt there is another problem, be careful not to run compressor very long like this without adequate freon/oil as it can destroy the compressor
Hopefully its still under warranty! if not here is a list of items to check out:
A refrigerant leak
defective pressure valves
defective a/c relay
See if it's the compressor by watching the compressor either spinning ( compressor is working ) or not ( compressor not working ). Compressor will not engage if refrigerant is low. Add R-134a ( 12 oz. can )
IF THE SYSTEM IS LOW ON FREON, THEN AFTER RUNNING FOR A FEW MINUTES THE LEVEL OF LIQUID IN THE ACCUMULATOR DROPS AND SHUTS OFF THE COMPRESSOR. YOU MAY JUST BE LOW ON FREON. HOPE THIS HELPS. THANKS FOR AN HONEST RATING AND FOR USING FIX-YA. BEST OF LUCK. PLEASE KEEP ME POSTED.
Hi, I would request you to please do the following steps to why the AC has stopped working. 1.Check to see if all the R-134a leaks out (meaning there's nothing in the loop to carry away heat). Leaks are easy to spot but not easy to fix without pulling things apart. Most auto-supply stores carry a fluorescent dye that can be added to the system to check for leaks, and it will have instructions for use on the can. If there's a bad enough leak, the system will have no pressure in it at all. Find one of the valve-stem-looking things and CAREFULLY (eye protection recommended) pokes a pen in there to try to valve off pressure, and if there IS none, that's the problem. 2.Make sure the compressor is turning. Start the car, turn on the AC and look under the hood. The AC compressor is generally a pump like thing off to one side with large rubber and steel hoses going to it. It will not have a filler cap on it, but will often have one or two things that look like the valve stems on a bike tire. The pulley on the front of the compressor exists as an outer pulley and an inner hub which turns when an electric clutch is engaged. If the AC is on and the blower is on, but the center of the pulley is not turning, then the compressor's clutch is not engaging. This could be a bad fuse, a wiring problem, a broken AC switch in your dash, or the system could be low on refrigerant (most systems have a low-pressure safety cutout that will disable the compressor if there isn't enough refrigerant in the system).

there.When a compressor is replaced,
two things are in fact being replaced - both the compressor and the refrigerant
(Freon) and if the problem is resolved as a result which of those two replaced elements
caused the original problem?Well you
will never know and so before the compressor is replaced you need to have you’re
A/C system recharged – it’s by far the most cost effective initial thing to do.In general A/C systems loose at least 10% of
their effectiveness each year through loss of refrigerant and so given the age
of your car; it’s the first thing to focus on.A professional A/C centre will also be able to tell you whether your
compressor is working properly after having a refrigerant recharge by the
monitoring the operating pressures in the A/C system.
