Blower motor intermittent

I have no experience with that specific blower but compared to others that one has too much internal friction. Typically blowers/fans will spin for quite a while before stopping. If there is a gap between the bottom of the white plastic part and the motor section check that it isn't jammed up with hair or dust. Ditto if you can see into the motor on the other side (which probably is not the case, the bottoms are usually sealed). That's a long shot, most likely the bearings are worn or the lubrication in the motor has evaporated or gummed up. If there is no dirt try to find a bottle of turbine oil (Ace used to carry it) and lubricate it with that. Doing that will usually make a fan or turbine work for a while, maybe even a year. However I have never seen that approach keep a blower/fan limping along for longer than that, and it worked best when the blower/fan was on 100% of the time, as in computer fans.

I should add that when blowers really go down the tube they tend to draw ever increasing amounts of current and in some cars the heat from the extra current has been said to melt connectors. So lube it now if you must as a stop gap measure, but order the replacement motor soon, so you don't also have to replace parts of the wiring.

 

Most likely you have a bad cabin leak like just about all g2's. The classic cracks in the runners on the roof terminating in the corner of the hatch valley will drip water right on the power connector of that fan rot the connector out and starve the fan power.

Get a flashlight and check in the 12 volt battery well for standing water. Then if the connector is corroded bypass the connector and butt splice the wires. This is very common on a G2.

As a side note i have also lubricated my blower fan with 3 in 1 oil they have an Electric motor viscosity grade oil. Says Electric Motor on the front of the oiler. Take the little seal off the back of the fan and squirt some of that in there if connector ok. It works good on your home compressor fan too although i have heard the new fans no longer have an oil port. Alas.

The 3 in 1 Electric Motor oil is sold at Lowes.

Your aware of the stolen cats right?

 

Are you thinking of the battery fan? I think the OP meant the HVAC fan under the dash.

Long way for water to travel from a hatch leak.

 

Yes thought it was the hybrid fan.....hybrid battery on the brain I guess..

 

I replaced my blower fan a couple of years ago. Same symptoms. It was working on and off for some time but since we have the AC always on Auto and my inexperienced son was driving the car it took some time to find out. Good news is just around $50 and 30 minutes work.

 

Yes cat theft in California is now epidemic. Go on YouTube lookup

Prius stolen

for the ca situation.

sorry thought you were referring to the hybrid fan. Mine failed too at 75000 miles and it goes intermittent before it fails. It’s very difficult to replace difficult on your body if your older as you have to get in a bad position to get it out so do not buy a used one or after market parts store one if you do you will be will back in there replacing it few months later.
Buy the oem one online or at the dealer. I like Olathe Toyota online.
