I have a 2005 EX Honda Odyssey that I take pretty good care of but it just developed an AC problem. R134 pressure is good, fan blows fine front and back, fan speed doesn't matter, no cooling at any fan speed, pump clutch never clicks on, can't find any fuse that might be blown, but I can test anything you want me to. At first it was intermittent, it would blow lots of cold air, but after we stopped the car and then started back up it wouldn't work again until after sitting overnight. After about a week of the intermittent behavior it stopped working completely. Any suggestion is welcome... unless it's to drive the car off a bridge.
Country: United StatesMake: HondaModel: Odyssey EXYear: 2005Engine: 3.5 L
Checked coolant with manifold, checked fuses, looked for the low and high pressure switches with no luck, also can't find accumulator
saw them, check all 3?
if it will save me from getting reamed at the dealer I'm comfortable doing just about anything. What tools do I need? do I test with car started?
I would think that seals it. Is there any chance of repairing the clutch or do I need to drive it to my dealer to have them replace it, or something in between.
You probably have a bad clutch coil which draws the clutch in which can be difficult to do in the vehicle without damaging the snout of the compressor. It could also be that the coild is fine but the gap between the clutch and the pulley is too large from wear. If it were just the clutch which had failed from to large of a gap and the pulley looked ok, it may be possible to replace just the clutch and adjust its clearance with the proper shims but that is a gamble. The best and most proper way would be to replace the entire set.If you watch the clutch when the a/c is turned on does it look like it jumps or acts like it wants to be drawn in? We could also check the continuity of the coil to confirm it is bad.A lot of times the shop may want to replace the entire compressor rather than attempt to rebuild the clutch. The ultimate choice is yours though. It's just that some shops don't want the bad PR if they charge for a new clutch only to have the old compressor fail shortly after. I've replaced many clutch sets though with no adverse effects.
