A/CCONDENSERFANRELAY
DESCRIPTION
The rear A/C conden ser fan relay for the r ear A/C
system is an Interna tiona l Stan da rds Organization
(ISO)-t ype relay (Fig. 3). Relays con forming to th e
ISO specifications have common physical dimen sions,
curren t capacit ies, terminal funct ions an d patterns.
The r ear A/C conden ser fan relay is an electr ome-
chanical device tha t u ses a low curr ent input to con-
trol the high cur rent output to the A/C condenser fan
for the r ear hea tin g-A/C system .
The rear A/C condenser fan relay is located in th e
rela y block in the rear A/C eva por ator hou sing.
OPERATION
The ISO-st andar d rear A/C condenser fan r elay is
an electromech anical swit ch that uses a low current
input from the rea r A/C cont rol modu le to cont rol the
high current output to the rear A/C condenser coolin g
fan. Th e movable, common feed r elay conta ct is held
aga inst th e fixed, normally closed relay contact by
spring pressur e. When the elect romagnetic relay coil
