RE: 98 jeep cherokee
P0443 is for cannister purge solenoid---open or short in duty cycle purge solenoid circuit
P1491 is for the radiator fan circuit

Cant fnd a code P0545 Found a P0645 A/C clutch relay circuit.

Being way2old is why I need help from younger minds.

RE: 98 jeep cherokee
The cannister purge solenoid has a flow chart to repair the code. If you have a test light or volt/ohm meter you can find where the problem is. Check t the connection for current. If there is current t the connector, replce the solenoid.(this is the short version of flow chart.)
As for the cooling fan. same thing. Start at the fan and see if there is voltge and current t the connection and work backwards until you either lose voltage and current. That is where the problem is. If current is at the fan connection, replace the cooling fan.
