My a/c clutch went a couple of years ago and I bypassed the compressor with a smaller belt. Do I have to do anything to the a/c system (unplug anything???) or will it be fine as is. Does this have anything to do with my previos thread for the gurgling sound in the core?

 

the compresssor needs to be cycled every now and then but if its bad i se no harm and nothing to do with gurgling

by not running it some, the seals and orings and such might dry out.
but - if you're not using it, or its broken, then it doesn't matter.

unrelated to air in heater core.
