A common problem with air systems in cold weather is condensation/water vapor freezing in the lines. If your drier is tired out and no longer pulling all the moisture from the air, it could be allowing enough water vapor in to freeze. Consequently, it'll also often cause the "slow to raise" codes since it usually clumps up and the compressor just can't push the air through. This is also generally why most of the compressors fail (along with overworking due to leaks).

If you notice it takes a long time to raise or lower, or the compressor runs for an extended amount of time, it might be worth replacing the dryer beads. Far cheaper than a new compressor.

 

Great point dj....

 

No problems now that the weather is warmer.

Last year I had the “air suspension pump” replaced. Would that be the same part as the compressor?
