Default Re: A/C blower fan won?t turn off

My 87 w/C68 did this. The blower motor control module fails in the "on" position and runs until the battery drains.

It looks like this; https://www.ebay.com/itm/19630392277...mis&media=COPY

The non-C68 cars have a Blower Motor Resistor which looks very different.

Default A/C blower fan won?t turn off

Interesting information: my car is a May 91 build car and had the 92 Delco 16061602 control module, not the 91 GM 12368387 module. Also does not have the 5A AC fuse. Given I?ve owned the car for 24 years, guessing this is how it was built. Image1714844253.414490.jpgImage1714844264.098098.jpgImage1714844288.678755.jpgImage1714844302.332422.jpg

And the module was the culprit. NOS from eBay.

I got one a year or so ago off fleabay listed for a Jeep Cherokee (exact same thing as for the GM cars) and it was maybe $13 shipped to me. No Corvette tax, exact replacement, 3 pin, works flawlessly.


For what it's worth, I just looked at the original one I took out (don't know why I kept it) and it is stamped Delco on it with a part number, then underneath that it says Japan, where it was probably made.

That?s right, I was trying to think what make/model car had the same unit, but it escaped me. 🤔 It was Jeep Cherokee.
Same, mine all good since replacing 2 years ago.
