Heater Blower Upgrade Question
 

All,

I went out and bought the heater blower
(http://www.off-road.com/jeep/tech/body/heater.html), and have run into a
problem or two. First off, both AutoZone and O'Reilley's only offer one
heater blower for that year, so there wasn't a choice between the cheaper
one and the more expensive one. It also does not come with a new fan.

The first problem was that the motor housing was a bit bigger than 3 1/4",
more like 3 1/2", but that problem is easily remedied. The second is more
serious, in that, after putting the old fan onto the new motor, I am unable
to put the heater blower back into the housing. The shaft on the new
heater blower sticks out about 1/4" more than the old one.

Any hints?

Go back to AZ and ask for the one without AC and compare. I think you will
find that's the ticket..

Re: Heater Blower Upgrade Question
 

I'm thinking you have the "premium" motor upgrade and are now in the same
predicament I was in. Your only option is to cut away part of the plastic
housing that the motor goes into. If I remember correctly, where the motor
goes in is kind of concave. Cut away ALL of the concave part so that it is
now just a flat opening. The motor should now fit without the fan catching
the sides of the housing. If it doesn't fit, add some foam padding (it's
like a foam insulator type stuff that is sticking on one or both sides). I
used this foam stuff as an insulator and it works nicely. You'll also have
to widen the firewall hole a bit ...after that's done get some heat-proof
silicone and silicone the motor on the engine side to seal it.

The biggest tip I can give you is to keep TESTING THE FAN out at each step
of reinstallation. The tightening of the housing and all of the
reinstallation procedures can flex the plastic housing and cause the fan to
rub. I had almost completely reinstalled it and when I went to test the fan,
it was stuck to the side of the housing again ...very annoying.

Good luck.

Re: Heater Blower Upgrade Question
 

at Autozone I had to go through a few GM cars to find the right one. All of
the Blazers had the same part number, I tried something like a 77 Camero and
it was the right one.
