Where is the air conditioning relay located on a Plymouth Grand Voyager?

Answer 1

The first model year of the 3rd generation Voyager and Caravan (1996) was cursed with the AC Front Blower relay positioned way under the dash up on the interior firewall behind the junction box and Body Control Module on the driver side. Chrysler refers to this as the AC Relay in the manual. This relay placement made the job of replacing the blower relay very labour intensive. There are 4 problems with the HVAC that came up on a regular basis with this model year and later model years of the 3rd Generation Chrysler Minvan/Wagon. 1997 and on finds the front blower relay in the "Power Distribution Center" next to the battery and is easily servicable as is the fuse. If your front blower only works on one or two speeds it is likely that the Blower resistor module is faulty (burnt) On the 96 and most 3rd gen later models it is located high on the passenger side firewall in the engine compartment. Right adjacent to the right front strut housing. If your blower is intermittent but all the blower speeds work when it does come on it is likely the relay is the problem. Very often because of the high current present on these circuits there will be a combination of problems that are heat related. Burnt or melted connectors at the resistor block are very common on higher mileage minivans. If the blower doesn't work at all it could be the 40 amp fuse, the relay fused open, the burnt resistor module and/or a faulty blower motor. The system may exhibit any one or combination of these faults. If you disconnect the blower connector from the blower behind the glove compartment you can check for 12 volts at the blower power harness. Turn on the ignition and check to see if there is voltage (12 volts) at the blower power harness. If you have your 12 volts there it is likely the motor is compromised. Good luck with your repairs.
