It happened a couple of day ago, that I get on the car, turn it on, turn the a/c on, & nothing is coming out of the ducts. when I got on the road I noticed that there was a little bit of air coming out & it was cold, but I had to get my hand close to the outlets to notice. then a couple of minites later, it started blowing normal againg.
2 days passed, & today the same thing. But after driving the car for a 2 hour trip, its still not working.
I had the blower changed about 3 month ago, so Im asuming is not that.
What else could be giving me this problem?

I would start by asking you this.....does it blow when you have the heat on? If not, time for another motor it sounds like?

It could be the blower control module. The check would be to put a fused wire directly from the positive battery terminal to the blower power connection when the motor is not working--making sure it has a ground--and seeing if it works.

I would start by checking a few items. The first is the pulley on the condenser. I had a similar problem with my air conditioning last year- wouldn't blow at all when the A/C was on, then would work, then wouldn't, etc. After a short while I started having this whining/belt squeeling noise when the a/c was on. I'd turn off the A/C and it would go away. Then it started getting more fluky, sometimes the squeal was when the A/C was off and turning it on would fix it, sometimes while it was on it would squeal and turning it off would fix, and sometimes nothing would fix. Finally, one night I was out with my g/f getting dinner and I smelled smoke. I pulled into a parking lot, popped the hood and noticed a huge cloud of smoke coming from my condenser. Shortly after, the belt snapped from the friction/heat and the car was stranded.

Long story short- first check the pulley on your condenser and make sure it spins freely.

Second, I would pop under your passenger side dash, and pull out your blower motor. I had a bad blower motor that I took out, cleaned out the coils and dumped a bunch of dirt out of, re-installed, made sure the connections were good, and it works like a champ now.

Good luck.

jseklund - the part you described is the compressor, not the condenser. Here'* a diagram:

It was the blower plug. I had chaned the blower a while ago. & the bad blower burned the plug. When the mechanic installed the new blower he didnt change the plug & it started giving me problems a few days ago.
I took the car to an A/C shop, & they told me what was wrong. They were real nice cause they didnt charge me nothing. so I went to a junker, got the plug & installed myself.
Guess I got lucky this time.

Thanks for reporting back. I learned from that.
