Heater switch question

[Bluebelles Mom]

I have noticed that the 4 speed switch in my car only works in the two highest speeds. I have not attempted to get at the switch...yet....I have a bad back and I would like to avoid 'under dash acrobatics' if possible. Could this be a matter of contact cleaning or are these things prone to old age failure? Suggestions?

Ok, I may have found what I needed to know via the search feature....should have gone there first, duh.

Check the blower motor resistor, its behind the control panel, not too difficult to get to.

Thanks. I think that is what I read about when I used the search feature. The resisters that are behind the glove box? I read the 'fix' someone used for splicing the broken wires back together. I will tackle that in the near future, I don't feel like working on the old girl today....this old girl needs a break.

That's one of the big dangers when working under the dash...hard to get to stuff and hard on the back. I think the best bet is a pair of knee pads instead of sitting.

second to last post here, i replaced the resistor pack recently and posted some pics. i imagine the resistor packs from all the hatchback and coupe tercels should probably fit too, though i haven't checked.

That looks pretty easy. I will be haunting pick and pulls soon to find a replacement. Thank you.
