Blower Woes

A new switch.

Spdloader

The resistor pak is the most common problem. Find it by looking at the blower motor cover compartment under the hood. You will see some wiring attached to the resistor pak. The part costs about $10. Dealers and after-market auto parts houses carry them. The resistor pak works on the ground wiring to the motor. The speeds of the blower motor are controlled by the resistors in the pak, with the High speed being a 'direct to ground' connection.

Hope this solves the problem for you......

....that's way better than what I had.....

I'm still living in the past where the resistor was done through the switch.

Actually, the resistors have been down in the air ducts for years. My 1970 Torino has the same setup. Keeps the resistors from overheating.

However, the current DOES actually go through the switch, so I would check that before replacing the resistors.

It used to be that a fan only working on high was an indication of a bad switch.

...and I should have said resistance in the earlier post instead of resistor.

the bearings are getting dry

good luck on getting any lube to them..............

Glad to have been a help! $32Can? Seems high, but the problem is fixed now, so......

About the chirp/gerbil: remove the rodents from the blower-motor housing. While you have the blower-motor out, spin the cage-fan. It may be slightly off balance and in something other than a circular spinning motion. The cage may be just touching something inside the compartment. Trash can accumulate inside that compartment. I've had that same noise and it's always been the cage hitting something(Trash)....usually a leaf. While you have it out and are spinning the motor, listen and see if you can hear that same noise. The bearings are lubed for 'life', as most motor bearings are these days. It is possible to get into them and re-oil, but it takes some patience to remove the cap. Most 'lubed for life' bearings have some type of wick media that 'holds' the lubricant. Re-soaking this media might solve a dry bearing problem. First check the cage for an interferance problem. You can also perform a current-draw test on the different speeds, but that's another subject.

Hope this helps.....

If the chirp is the motor bearings, don't even try to open the motor. Just drill a small hole above the just above the bearing "dimple" and oil it with

It's getting difficult to find non detergent oil. Wal*Mart, Checker, and Auto Zone have it. If you're lucky enough to find 20 weight, it's better. I can only find 30 here.
