Hi John;

    I assume from your post that it is the fan that is squeaking. I had a
similar problem on my '86 5ktq at about 160k km. In my case it was the front
fan motor bearing. It squeaked with either A/C or heat when I cornered or
hit large bumps.
    I solved the problem by drilling a 1/2" access hole in the plastic
heater box above the front bearing and placing a wire through the hole and
behind the fan wheel until it touched the motor shaft just in front of the
bearing. I ran drops of WD-40 down the wire onto the shaft. This silenced
the squeak. It also sounds easier than it was!
