Yes, you need to get the right blower motor, free of charge, without any additional shipping fees. However if for some reason a seller won't ship you out a new one that correctly fits your vehicle free of charge. Or you can't get back to the store where purchased.

Then I would swap blower motor housings, using the housing from the one previously installed..

There was a video of a person who had to do that because the "housing" of the blower motor he purchased was taller than the one that oe one for his vehicle.

It wasn't that big of a deal he just removed the motor from his old blower motor "housing", cleaned it up and painted as there was some rust and installed the motor from the newly purchased blower motor into his old case.

I can't find the link to the video which was nicely produced and showed all the details of him performing the swap.

For some reason he couldn't return the new blower motor he had purchased from a store. So what would you do? Throw away a brand new perfectly good blower blower motor and go out and find another one that fits correctly?

I was just making suggestions in case, for what ever reason, the OP isn't able to get another motor blower free of charge or a full refund including original shipping charges.

Actually these blower motors are usually fairly simple to repair. What normally wears out are the brushes and bearings. If you have spare parts replacement isn't very difficult.

The automotive parts manufactures don't make parts readily available as they want to sell you some more of their new or refurbished motors.

New parts are actually out there at places that sell electric motor parts, however if you don't have a part numbers requires measuring and comparing size and dimensions to new parts. Such as the bearing e.g. most likely uses a common size bearing a specific size. Same with the brushes most likely uses a very common brush size.

One of a motor primary part is the rotor which is basically separate isolated windings each connected to a segment of the commutator, the segments of the commutator which should not have any continuity between them are divided by the commutator grooves. If the commutator isn't too warn the grooves can be cleaned out using a sharp instrument such as flat head screw driver.

It's often a ~15 min job to repair a motor. You just need to remove the rotor to expose the rotor, commutator, brushes and bearings. The brushes and bearings usually can be easily removed and re-installed with new one or ones in better condition such as salvaged from a used motor.

However since most of the Jeep blower motors are comparatively inexpensive most people just pickup a new or refurbished blower motor, or one from a salvage yard for under $10.00.

For some vehicles this isn't true. A typical cost of a new blower motor is $350.00+ So repairing one for a few dollars in parts would make sense. The main concern is trying to find and match parts, where a motor repair person will likely have access to. If no part numbers they would just measure using calipers and find the same size brushes and bearings.

New brushes and bearings usually aren't very expensive.

For what ever reason jeepcherokeeforum.com won't allow me to edit my previous post.

I was going to add if you have an expensive blower motor that has worn brushes and bearings. Hardware stores such as ACE and others usually carry spare motor brushes. To find new replacements you can either measure the existing worn ones or take the worn ones into a store for a comparison. They just need to be the right width and not too long so they can fit into a spring loaded brush holder.

Trying to find bearings is similar you can measure or bring into a store to see if the bearings can be matched. Bearing type OD, ID and width should be the same. Motor manufacture usually use common parts, some with different sizes to fit the rotor shaft and motor housing.

Years ago it was very common for people to rebuild motors, alternators, starters, fans, etc. and I remember at one time more parts were available. Sometime back in the 50s and 60s products were to built to last ~30 years and longer and designed to be repaired with a good selection of spare parts.

Today's society and manufacturing is aimed more toward replacement rather than repair. Many items on the market are becoming less repairable because their designed for manufacturing costs, some require expensive specialize tooling, etc. But luckily some items such as blower motors, alternators, starters, etc. can still be repaired if one is able to find spare parts.

A new Mopar blower motor is going to cost at least $90.00 or more. Usually OEM parts such as Mopar are manufactured to last at least 125,000 miles and are usually better quality than an aftermarket.

But for the price many of the aftermarkets are considered to be OK, whether they'll last 100,000 - 125,000+ miles I don't think anyone knows for certain. Aftermarket alternators normally don't last nearly as long as OEMs such as from Mopar which I've see on the Jeep with 150,000+ and some 200,000+ miles.
