Re: after run relay
Subject: after run relay
well i just fried the 2nd after run relay in not nearly enough miles ;(
first time: i parked the car in the garage, after run came on, i went into the
house and returned to a dead battery and a brown relay (it was the short grey
one in the main fuse box)
today: i parked at a store, after run came on, i went in and returned to hear
the fan on (full speed) after it should have been shut off.
once again, the relay was turning into a roasted marshmallow.
i haven't gotten home yet to consult the book of bentley, but i'm going to
start by looking for the sensor at the bottom of the upper coolant nozzle
on the engine block. the coolant is seeping from either the threads or
the sensor housing itself and probably filling the rubber boot that has
a bunch (8?) of wires coming out.
my radiator fan and fresh air blower are competing to be the first to
i'll be looking at it tonight so any ideas for either problem would be
Make sure you're using a suitable-rated relay. Not all relays are created
equal, even if externally they look like the same configuration. Anything
touching the radiator fan should be 40-Amp rated, at least. Otherwise,
you will be arcing and gradually welding the relay contacts together,
which in turn results in terminal meltdown, just as you're seeing . . .
