Cleaning drain hose for air conditioning

Ok new problem my front air conditioner drain hose is plugged. Usually a few shots of air clear the line. This time it did not work.  Any suggestions.

Might have to get up on the roof and take a look at the drain pans under the A/C shroud. On my PT, the drain hose from roof to ground is 1/2" ID tubing, pretty large to be clogged up. Your clog may be in the drain pans. Also, my drains work sometimes, and the A/C condensate runs off the roof sometimes. Maybe the rig has to be dead on level.

Will check that.  Seeing as I’m not level may be the biggest problem.  Thanks

Get a roll of weed trimmer line and use that to snake the drain out.

Lacking the weed trimmer line, I took a piece of (clean) PVC tubing and used it to blow air thru the two drain hoses. My lungs worked as the air compressor. Took a bit of work, but, the drain hoses were clear.

When I replaced my AC’s it was found that the drain hose on one of them had a pinch in the drain hose, restricting the draining, in the ceiling, above the air filter.
