Heater blower question

[screamingbuick]

Hi guys, my son just called and said the heater fan would not shut off, so he unplugged it under the hood so it wouldn't kill the battery when he was getting a haircut. He called me back 20 minutes later and said he plugged it back in and now it wont come on, any idea's where to start looking for the issue?

Are you talking about the COOLANT fan?

no the Heater blower for inside climate control.

OK. It's the digital climate control? The one with the LED control panel? If so, the module is toast. They overheat and burn up.

Look at:

CEI - Casper's Electronics, Inc.

and click on INSTALLATION

Sorry miss spoke, its not the digital climate control, i just meant inside heat blower fan.

 

[screamingbuick]

regular analog controls, slide switches and 3 or 4 speed heater fan switch in dash.

Fuseable link burned out is my guess.

 

[screamingbuick]

where would the fuseable link be?

Looking around I'm thinking it may be the blower motor relay crapped out, is there a diagram as to where this is, also is there a decent wiring diagram for an 87 GN here somewhere?
