2003 Volkswagen TDI AC Works Sporadically

For the last month, when I turn my air conditioning on, it will blow cold air for about a minute before it stops blowing any air at all and has a faint ticking sound that sounds like it's coming from the blower motor. This is true whether I turn it on full blast, medium, or low. When I turn off the air conditioning and wait for a minute or two, and turn it on again, the problem repeats - it will blow cold air for about a minute before it stops blowing any air at all and starts ticking. I can go on doing this indefinitely.

Any thoughts? Thanks!

It sounds like the blower motor itself is bad and may just be overheating. The best thing to do is access the motor (not fun) and check for power to it when it stops running. If there is power, replace the motor. If there is no power, the it could be a bad relay.
