Heater Question

[froggyrocket]

All -

I've got an '88 L where the heater blows on settings "2" and "3" but not on "1".

Anyone else ever had this problem?

Looked at my shop manual and I can't tell if this is the heater motor blower switch or the blower resistor. Am I out in la-la land?

Any help would be appreciated. Thanks.

it's the blower resistor failing, you'll need to locate a replacement. my '88LX does the same thing.

Could be the resistor or the switch. If you have the Haynes I believe it gives the resistance values to check the resistor pack. My MX6 lost 4, then 3, then 1 and all I had left was two. Took the switch apart and cleaned the contacts (after the resistor pack tested good) and it works like new again. But thats not to say that its not the resistor pack, I've had a few of those fail as well on various cars. The point is to properly diagnose the problem before throwing parts at it
