Blower Problem

[mjgates]

Toward the end of last year, my blower stopped working. I checked the fuse and it appeared fine. I replaced it just in case with no luck. I'm about to start working on it in the next week or so to get her ready for the season. Anyone have any suggestions on where to start to troubleshoot the issue. When I turn it on nothing happens. No sound. It's as if I didn't do anything at all. Not sure if the problem is more likely in the wiring or the motor itself and the best place to start. My mechanical skills are novice at best, so any help is appreciated.

Re: Blower Problem

go to auto store and get 12 volt light tester, turn blower on and go back and ck wires at blower. hook the clip on the light tester to good ground on engine or battery if it is long enough negitve side - then take the pointed end and make contact with wire at blower, your ground will be black or brown make contact with other one. if it lights up blower is bad ,ck afew times to make sure. then i would take it out and make jumpers to batt. just to make sure. if you have no power there then go to fuse and ck it with tester, then ck your switch. good luck.

Re: Blower Problem

just an idea but have you tried to turn the blower by hand? Many of these blower motors have bronze or brass bushings and they wear out and the armature rubs the stator and stops the motor from turning. The only fix is to replace the blower motor. Check for free rotation, "by hand". Many blowers run constantly so they tend to wear out the bushings. You can get motors with ball bearings but they cost more.

Re: Blower Problem

Disconnect the blower and wiring and hold the + & - directly onto the respective battery terminals. If the blower runs, it's a wiring or switch problem.

If you replace the blower, pay special attention to the airflow directional arrow on the blower housing. The bilge hose should be attached to the inlet and the outlet should go to the louver vent.
