I took a drive to see family today. On the way there the AC was working great. Nice cold air coming from the vents. When I went to leave and turn the AC on, the blower does not work. I am able to turn it on and the controsl light up. I am and use all the controls, the blower control, but no air comes out of the vents. Any suggestions, as to what might be or have caused this. Any help is always appreciated.

Regards

 

Does anyone have any suggestions regarding this issue....

 

Blower motor under the glove box.

 

Check the fuse, then take a test probe and verify if the power is getting to the blower, if it isn't, you may have fried the control unit, if you have power to the motor then it is fried.

 

This is the second most common thing...ok third most common thing go wrong on a DII.
Do a search on the forum for this, tons of threads on it out there.

 

Palmetto Disco sent me this and it worked great. Give it a try.

Like some on this forum, I had an intermittent working blower that finally died. One of the fixes (for some) from past threads was to install a new fuse box. Somehow the connection through the fuseblock to fuses 6 & 7 fails. Fuse 6 (25 amp) is rear A\C blower, if equipped, and fuse 7 (30 amp) is the front A\C blower. Both of these were dead on mine as well.

I looked at the engine bay fuseblock, also. Fuselink 4 was good, however, the connector (on same fuseblock) it sends power to was dead at the Brown\w Pink wire. This wire goes to fuses 6 & 7 in the passenger fuseblock.

I ended up running a bypass wire to each fuse directly from fuselink 4 (cold side, next to side of fuseblock), with an individual blade fuse holder on each wire. I put a spade connector on the ends and tried plugging in to the cold side of slots 6 & 7. It still didn't work. This fuseblock was bad, also.

I pulled the fuseblock and attached directly to the wires out (cold side) on the back. For fuse 6 (rear blower) pull connector 585, first in line, brown with three wires. You want the Yellow\Green wire. Pull the white retainer clip and dig out this wire with a small screwdriver. It has a spade receptor, of which I attached my 25 amp bypass wire. Put clip back and replace connector. The next connector back is 584, pull it. It is also brown, but has five wires in it. You want the Brown\Red wire. Pull it out the same way. I connected it to the 30 amp bypass wire. Fix and replace the connector. Button everything up.

Success! I now have cold air blowing, front and back. Less than $20 for wire, individual fuseblocks, and connectors.

The picture is showing the back of the interior fuseblock. The drawing is of the engine bay fuseblock near the battery.

As for the interior fuseblock, check fuse 7 for power with a test light (with A/C on).

If you have power at the fuse, remove the nut at the top of the fuseblock, pull the top of fuse block down to reach the back. Pull connector 0584 (see photo), locate the brown with red wire. From the location of that wire in the connector determine which pin on the fuseblock that wire attaches to. Check that pin for power from fuse 7. If you don't have power then your interior fuseblock is bad (not sending power from fuse 7 to the rear connector). Buy a replacement fuseblock, or bypass it like I did (see below). If you have power on this pin, then either the voltage is less than the blower needs to run or there is a loose connection/cut wire.

If no power at the fuse, remove the nut at the top of the fuseblock, pull the top of fuse block down to reach the back. Pull connector 0581 (see photo), locate the brown with pink wire, test this wire through the connector with the test light (with A/C on). If you have power then your interior fuseblock is bad (not sending power to fuse 7 from the rear connector power supply).

Buy a replacement fuseblock, or bypass it like I did.The wires in the connector are locked in with a thin white plastic plug. Pull this plug out with needlenose pliers, take a small flat blade screwdriver and dig/pry the brown with pink wire out. It will already have a spade bit receptor attached.

Do the same for connector 0584, for the the brown with red wire (This wire is direct to the blower). Buy a 30 amp inline fuse, attach spade bit tips to both ends of the 30 amp inline fuse and plug into the 2 wires you dug out. The blower should work now.

If you don't have power at the brown with pink wire (connector 0581), then you need to check the engine bay fuseblock (see drawing in linked thread provided earlier). Power starts at fuselink 4 and exits the fuseblock at the connector shown through the said brown with pink wire.

 

The easiest thing to do is first test the blower. Pull down the "paper" cover under the passanger dash and the blower will be right there. Three screws and pull it down and unplug. Hook a small jumper to the positive and negative from your battery and if it spins you can eliminate that. Hold on it will be blowing full speed if it is working and might try to jump out of your hand when it is powered on. If that is working than go to the steps above to determine where the break in power is. Good luck!
