Default 2003 Dream Cruiser2 A/C blows weak and then strong cold air

Hello!
I have a 2003 Dream Cruiser2 - 150,000 miles and well maintained.
I noticed recently that my A/C is blowing the cold air weak and then strong intervals. The air is cold, no smoke coming out of the vents but it concerns me that it is blowing not at a steady pace. I have not noticed any issues with the car idling rough or stalling.
Any ideas?
thanks!

At 150K surely uou have had the timing belt changed, I hope. But back to the cooling problem, it most likley the 2 speed radiator/ac Condensor cooling fan that is the problem.
I would guess that sitting in traffic the air is warmer and it cools ok driving down the highway at 50mph.
Keep an eye on the temperature guage and avoid overheating, Just one instance could cause big problems.

Thanks for the input. Timing belt has been changed and all recommended maintenance has been done.
The strange thing is that the air is cold with the weak stream of air. The car is not overheating. I always keep an eye on the gauges (she is an old gal and I want to keep her running).
Thanks!!

Are you saying the A/C is cold, but weak airflow at times?
I think you are low on refrigerant, and the coil is freezing up and the ice blocks airflow.

If the inside fan isn't blowing enough air through the evaporator it can freeze up. Does the inside blower work with the 4 speeds?
When you put it on max the the inside air blow the most cooling
If the charge is not correct it could also be causing the evaporator to freeze slowing air flow like Quicsilvedon said.

I was low on refrigerant. Very low.. they did a A/C service to the car, checked for leaks, etc.. they had to put in .8 of refrigerant in my car.
issue resolved..
thanks all!!
