Blazer motor upgrade on 95 YJ - Necessary?

I recently purchased a body tub from a 1995 YJ. All of the air intake and heater parts were included, including the heater motor and heater core. I was planning to to the Blazer upgrade, but the instructions on the web sight advised that the upgrade is for 78 - 90 CJ/YJ's. With a 95 heater motor, do I need the Blazer upgrade? Do the later YJ heater motors "blow" more air than the older style? Any advice would be greatly appreciated.

My heater in my 95 YJ works unbelievably well, especially when compared to my old CJ motors...I wouldn't bother swapping it out for the blazer motor.

The GM Heater Motor is a very powerfull blower motor.

Go to the Autoparts Store and ask for an aftermarket blower motor for your year YJ an see if it matches one of the following numbers:

Vendor...............Part #
ACI..................33892
Everco...............M892
Murray...............208971
4 Seasons............35587
Siemens..............PM102E (This is the Maker of the motor)
NAPA.................455-1039
Factory Air..........35587
Kragen...............35587
YJ replacement.......PM102E

Fits, except for a long shaft
NAPA.................455-1076
Shucks...............33892


The above part numbers are for the GM Blower motor. I suspect that the aftermaket YJ blower motor would be the same. Check it out and see what you find and we'll all learn something.

Is it worth doing the upgrade? Humm... that's a great question seeing that you have the part already accessable, and it's used, an maybe gummed up and turning slow... or may not. Change the motor now and you have piece of mind.

How much is peace of mind worth to you?

If it's the same as a 91, it's already a bigger motor and it's wired different. It has a power and a ground wire, the old motors are grounded through the case. They (the newer motors) are also more expensive.
