Thumbs up CJ-7 Heater upgrade!!!

: I just finished my cj-7 heater upgrade. I installed the chevy blazer heater blower. I was suprised how quick and easy the whole thing was. took 2 hours start to finish. 2 frosty adult beverages and one pit stop. the hardest part is making sure you get the right blower motor. it seems that the part numbers for a 73 chevy blazer are interchanable and one of them is 1/2 inch to long. This resulted in several trips around town to find the the right one. but then any time I work on the jeep its a manatory 3 trips tothe parts store Advance auto had it for $19. now when you turn the blower on you MUST wear your seat belt. be warned that thing blows harder then pamala Anderson on video tape.

Happen to have the part number on hand? It's on my list of things to do this winter.

1986 CJ7, 4.2 w/4.0 head, TFI-HEI hybrid ignition, Clifford manifold w/Holley 390 w/cold air intake, OBA, 4.5" lift, Woody CV shaft and Tattons in front, 4.10 gears - lunchbox in front, Truetrac in the back, twin-sticked, blower upgrade for running topless, trying to keep it simple.

It's just a Jeep, and if you don't wheel it once in a while, it's not even that.

Agree with "gosupes". How about a part number and store name? Online writeups list different #'s sometimes. Another first hand experience on the correct number would be appreciated.

Clicky

Autozone's PM102A worked for me. The one the writeups call for the most (PM105 IIRC) was on the shelf right next to the 102A. Definitely a difference in the cage shaft length.

The 105 compared to OEM:

i don t mean to hijack but anyone know where to get the cage wheel from? mine broke into 100 tiny parts and i need a new one for winter.

Small, fine shavings are ok, large chunks are bad, huge chunks with part number stamped on them are real bad.

I'm thinking you'll probably have to junk yourself one if no one has a spare laying around. I've never seen them for sale anywhere, but I'm sure someone does somewhere... I took some measurements on mine when I had it out for the swap:





Just about any cage with those approx measurements should work. Now there's the matter of fin direction, but you should be able to make that out with the pieces you have left....

or if not, here's a pic...

PM102A made by seimens works the pm105A is to long. napa and advance carry both numbers . advance also had a blower motor made by "factory Air" part number 35587 this is the one I used. $19.88 ask for a 1973 chevy blazer blower 2 or 4 wd with air or without just check the box number and the part number on the side of the motor. just in case it got put in the wrong box when someone returned it to the shelf.


get your own model for the video
