SOURCE: EFI underhood relay

I would replace the relay that gets hot, and make VERY SURE that the relay pins fit real tight in the female receivers for the relay. A *** slight *** amount of clearance at the connection will arc & def heat up the relay. Once relays get really, really hot, it, at times, they may no longer be reliable.

SOURCE: relay for turn signal buzzes when turned on

The only reason that a relay buzzes is it is getting either a poor ground or a lack of power,clean your body grounding points and make sure you have a full 12v supply to the relay.If you have low voltage to the relay check the fuse and clean off any corrosion,if not that replace the turn signal switch./

SOURCE: 2006 chrysler pacifica air blinder

the blower relay switch controls the blower motor,this sounds more like an air blend switch on the heater control head on the dash,not making the switch over in that could be the air blend door motor on the heater duct under the dash on the passenger side.this can be checked with a scan tool that has the capability to communicate with the bcm computer on this car.
