i have a 86 GL and pretty much my fans wont blow. i checked the fuses and they all work then i ripped the car apart and found im not getting power to the switch to select fan speed or the blower motor. any ideas?

Have you checked the fusible links? Make sure they are tight and have continuity.

 

Next - the fan is only powered when the climate control selector is in any posistion other than "off" so you'll want to check for power to your climate control panel and insure that the buttons are working properly. They are dual-purpose in that they switch on the blower circuit as well as reroute vacuum supply to the flapper-door actuators.

 

If you took it apart be aware that you need the climate controls connected while you are checking for power at the switch or blower motor.

 

Obviously any time you are checking power at the switch or motor you will need to have one of the modes other than "off" selected.

 

Besides the switch and motor there is also a resistor pack down in the ducting near the blower that provides every fan speed except high.

 

I haven't looked at the schem. so I don't know if the switch is switching the ground or the power to the circuit. Someone will probably know or I'll dig out my book.

do you happen to know if a newer loyale climate control would fit in a GL? they look about the same but im not sure and they are all i can find

Yes - they are identical. The only difference is the way the switches look and the shape of the slider knob. You can pop out all the switches and pull the knob off and replace them with your original and it will look identical.

 

Oh - and the backlight bulb is green on the newer one's. Again put your's in if you want the white illumination.

 

There are differences in the design of the slider mechanism and strangely enough BOTH of the designs have serious flaws that result in them breaking. The intersting thing is that you can take the plastic slider out of the early control, fit the flat roller wheels from a later style control to it and install into the later model slide rail to make a superior control mechanism. The problem with the early one's is the shape of the roller wheels, and the problem with the later one's is the design of the slider. You just have to take bits from both to make a good one.
