Question 1989 260E Cabin Blower stopped working

Greetings!

Is there a post, link or directions as to troubleshooting a 260E cabin blower function or in my case lack of function?
My blower stopped working yesterday and with the Chicago winter approaching I need to at minimum be able to defrost the windshield.


Thank you!

Check the fuse on the left front inner fender well near the strut tower under a black plastic cover. The cover will have a slightly heavy gauge wire coming out of each end. The fuse is a metal strip about 1/4" wide by 1.5" long and is held in by two screws.

The fuses often get hairline cracks but still look good, replace it, test it with a voltmeter or use a jumper to test it. Replace it if bad don't leave a test jumper in place.

Good luck!!!

Try wiggling your ignition key. Sometimes with age, the ignition switch will not return fully from the crank position. There are separate contacts in the switch for blower power.

Check the voltages at a connector above the brake booster which has heavy red and black wires and a thinner yellow wire. You should have 12 volts between the black and red wires. The yellow is the fan speed control voltage coming from the pushbutton unit. It should have about 1 volt for low speed to about 6 to 10 volts for high.

If voltages are correct, then you have a problem with the fan control module (located below the blower) or a bad motor or both. Remove the windshield wiper mechanism and remove the blower cover. Disconnect the blower wires and connect 12 volts directly to the motor to see if it runs.

Also check fuse #5 in the fuse box under the hood.

Got it

Thanks for the responses. It turns out that the fuse located on the left strut tower was cracked. New one is on order, thanks again for the tips!
