Having multiple issues. It started with P1745 line pressure to high for to long and jeep does not shift. It then started over heating. Changed thermostat, fan relay and temp control sensor. Took to shop and they did a block test and all they said was it failed and to put a new motor in. Ac started blowing warm air so I recharged it. Fan was not coming on. I can turn ignition off and back on and fan starts. Not sure what to check next. Looking for help.
