I have been trying off and on trying to troubleshoot the problem with my AC. The AC blower and fans all work fine. I have charged the system. When working correctly it blows the the coldest air you could ask for. However, to get the AC to start blowing cold air I had to hit a speed bump fast and hard, run over railroad crossing, or take a turn sharp and fast to get the thing to kick in and this only works maybe 30% of the time. Any suggestions or advice is welcomed.
