I have a malfunctioning blower relay in my 1986 corolla (4 dr, hatch 1.6
engine).

The part number is 85913-30020

At this point I am using a wire to connect the two power leads.  Will this
cause any long term damage?  Is there a fuse or breaker in the system to
prevent overload problems?

I have noticed that one of the main functions of the relay is to shut the
blower motor off when the ignition is off.  With the two wires I have to
manually disconnect them to get the blower motor to shut off.  Actual;ly,
the fan works fine other than that – at all 4 speeds, etc.

Does anyone have such a part at a reasonable used price?  Otherwise I may
just go with the wires
