My 2000 Blazer has a strong amount of air blowing but it is not cold. At the end of the season last year it seemed to be working just fine. There has been several repairs made to the vehicle since I last used the air and I was concerned that there could be a vacuum hose to the air conditioner left off or loose. The dealership suggest that dye be ran through it w/ a rather costly diagnostic fee, so I thought if I could check to see if this is the problem before going to that expense I would. Where can I find more information on the location of the vacuum hose on my vehicle and are there any other suggestions you may have before I resort to taking it in to the dealership?

Well, as far as I can remember the only vacuum hose if it has one will be on the control panel for the temp and switching from vent to floor etc.

Check to see if your A/C Compressor is Kicking in, and watch to see if it kicks in and out every few seconds, if it does then you are most likely low on freon.

If it doesn't kick in at all then look for Blown fuses and/or Bad Relays.

You can purchase a leak detection kit at your local NAPA Store. You can find the leak on your own if you have a leak. Sometimes if the A/C isn't run for a while it will loose freon and just need a recharge.
