Question about Buick Enclave
2008 Enclave - HVAC blower stopped working...40A blower motor fuse in engine bay is good, but want to check the 15A fuse labeled "HVAC" in the interior fuse panel (behind glove box), but cannot access it enough to remove and check the fuse due to rubber sound proofing material and the tight, curved fit of the fuse block (extremely poor placement/access for this row of fuses). What does this 15A fuse do...is it worth trying to remove to check? Does it turn the blower on/off? The instrument panel works (ie - the fan indicator lights up to show the speed of the blower), so does this mean the 15A fuse is good?

If you know the fan works with direct battery voltage and you have no voltage at the fuse block then you have a problem at the fuse block. You need to remove it and check for corrosion or a short. This could also have something to do with your radio and buzzer. Pull the fuse for the radio and remove the buzzer and then check to see if your test lamp lights across the 25 amp fuse opening for the blower.
Also with fuse in place check for voltage at the yellow/brown wire going into the blower motor switch. Just cover all your bases before going at removing the fuse block.

Did you find out a solution to your problem? I have a 1996 trooper that is showing most of the same symptoms that you have. I'm curious as to your fix. Was it simply a bad ground?
