CARAVAN, TOWN & COUNTRY, & VOYAGER The dual, 2-speed cooling fans operate simultaneously and are turned on when coolant temperature becomes excessive or A/C head pressure indicates A/C operation. Fan should not operate during engine cranking. With A/C off, cooling fans turn on or off when coolant temperature sensor signals PCM that coolant temperature has reached a specified temperature. Regardless of vehicle speed, fans will turn off when coolant temperature drops. COOLING FAN MOTOR NOTE: If fan motor is noticeably overheated, system voltage may be too high. Check charging system. Disconnect cooling fan motor harness connector. Observe correct polarity. Connect battery voltage to fan motor harness connector terminals. See Fig. 1 or Fig. 2 . If cooling fan motor fails to operate, replace fan motor.

Model(s): 1996-99 Chrysler (NS) Town & Country 1996-99 Chrysler (GS) Voyager 1996-98 Jeep (ZJ) Grand Cherokee 1996-98 Jeep (ZG) Grand Cherokee (International Market) The Memory Seat/Mirror Module (MSMM) (on ZJ/ZG the module is for the seat only) detects and remembers where the end of seat travel (called “soft stop”) is in each direction. A soft stop is set in MSMM memory when the position sensing feedback voltage, controlled by a potentiometer on the motor end, fails to change. The feedback voltage potentiometers vary the position sensing feedback voltage based on seat position/movement (no movement, no change in position sensing feedback voltage). The seat motor automatically stops at the soft stop on any subsequent movement so the motor does not run into a stall condition (end of travel). The soft stop limits will be updated any time the MSMM senses a mechanical stall (such as when something is stuck under or behind the seat that causes the seat to stop moving). These soft stops can prevent the seat from being able to have memory positions set over the full range of travel. Also, positions that were previously programmed to locations beyond an updated soft stop limit will not be recalled as they are “out of range.”

Cooling fan motors operate when Powertrain Control Module (PCM) determines fan operation depending on crankshaft position, Engine Coolant Temperature (ECT) sensor, vehicle speed, Intake Air Temperature (IAT) sensor, A/C switch and refrigerant pressure switch inputs. Cooling fans receive power through the cooling fan relay. Condenser fan operates only when A/C compressor clutch engages except 2004 models with turbocharger which uses dual fans for engine cooling with or without A/C operation. See WIRING DIAGRAMS . COMPONENT LOCATION For component locations, refer to illustrations. See Fig. 1 -Fig. 3 .

NOTE: NOTE: For connector terminal identification, see CONNECTOR IDENTIFICATION . For circuit identification and wiring diagram, see GRAND CHEROKEE wiring diagram in WIRING DIAGRAMS article. DTC P0320: NO CRANK REFERENCE SIGNAL AT PCM is monitored during engine cranking. DTC may be stored in Powertrain Control Module (PCM) when PCM senses no Crankshaft Position (CKP) sensor signal during engine cranking, and at least 3 Camshaft Position (CMP) sensor signals have occurred. Possible causes are: defective tone wheel/flexplate, defective PCM, defective CKP sensor, defective CMP sensor, defective connectors or defective wiring. 1. Turn ignition on, with engine off. Using scan tool, read current CKP count and attempt to start engine. If current CKP count does not change while attempting to start engine, go to next step. If current CKP count changes while attempting to start engine, go to step 16). 2. Turn ignition off. Disconnect CKP sensor connector. See Fig. 26 or Fig. 27 . Clean and/or repair connector as necessary. Turn ignition on, with engine off. Using a voltmeter, check voltage on CKP sensor connector, 5-volt supply circuit (Orange wire). If voltage is more than 4.5 volts, go to next step. If voltage is 4.5 volts or less, repair open 5-volt supply circuit. Perform TEST VER-5A.
