Just discovered I have a freon leak in one of the pipes to the rear A/C on my '05 EXT Trailblazer. It is right above the fuel tank. I looked for previous posts and found someone had heard there are now flexible replacement hoses available as an alternative to seperating the body from the frame to install new rigid lines. Does anyone have any first-hand knowledge of this?

My '05 XL leaked as well, I took it to an automotive AC guy. He had a kit that fixed the line(S), I assume, it was a cut, flare and connect deal. I don't remember the price, but I recall it was not a lot. Something like $20 for the kit, a little labour and a recharge.

These guys have splice kits as well

All's well that ends well. Got the new flexible lines from autocoolingsolutions and got them installed. It was somewhat tedious routing the large diameter line around the fuel tank and over the rear axle but all-in-all not that big of a deal. Payed special attention to avoid pinch and abrasion points. Took it to Midas today and they were able to charge it up with no problems. I'm glad I took the harder and costlier approach because we really like our TB and it is our family vehicle so I hate to take short cuts on repairs at this point.
To find out if it's low, turn on the a/c, disconnect the low pressure switch on the receiver (the can on the passenger side) and short the two connectors for a few seconds. If the clutch engages, it's low on refrigerant and still have a leak. If it still doesn't engage, could be a problem with the relay or the clutch itself.
