I am having a issue that I cannot find any info on surfing the internet. Similar-but not my situation. I have a 2010 Chrysler Town and Country Touring 4.0L and my freon became low. Discovered a small leak at a connection point on one of the rear lines that I will be repairing but want to make sure I can resolve the other issue first before spending time and money on the leak. When adding freon it will hold a charge for several days-enough to blow cold air. Problem I can’t figure out is while monitoring the manifold gage (before and after adding freon) the low and high side will rise, then the fan turns on in front of the condenser and then both pressures lower. Then the fan turns off and both pressures rise again. This whole process takes about 40 seconds and it never stops. Even when I added freon to the proper PSI (for the current ambient temperature at the time) both the low and high side continue to rise and fall about every 40 seconds. The pressures that it would rise and lower to were: low side would rise to about 35 and the high side to about 250, then the low side would lower to about 22 and the high side to about 150. Any help would be appreciated.
