97+ XJ Blower Motor Removal and Replacement

before you start laughing, I know this is a simple operation, but some folks haven't changed out blower motors as many times as the rest of us. I figured I'd help out all those in the "fan does not blow" boat.

If your heater/air conditioning fan has a mind of it's own or if the blower motor only works if you hit it with a blunt object, then this is the fix.

First of all buy a new blower motor. You can find them new for between $160 and $220. I'm sure some of you can find a better deal. Personally I think the prices of the 97+ fans are insane. I remember getting the old style ones for next to nothing.

Next, if it's this cold out find a heated garage.


The tools you need:
1 1/4" ratchet with an extension and an 8mm socket.


Now, you should disconnect your battery. I chose to live dangerously and skipped this step.

Locate your blower motor. It's under the hood on the passenger side firewall. Reach in and pull out the plug.


Remove the three screws (the brightly colored stars highlighting their positions) holding the fan in.


Now it's time to remove the fan.


This can be a bit tricky, but if you think of it like a chinese puzzle and get the flanges for the screws out around the wire bundles, you'll be ok.


There, one crap motor and fan.

Now it's time to pu in the new one.


Wrestle the new unit in past the hoses and bundles.


Push it in.


The flanges at the bottom need to go in first.


Put the screws back in, starting them by hand.


Once the screws are in tight, plug in your new fan.


All done.


Remember to reconnect your battery (if you chose to play it safe.)

Get in your mighty 97+ XJ and feel the wind whistling through your ankles!


There you go. I hope this helps at least one person out.

What were the signs of it going bad for you? I just had an issue with mine that on the lower left corner the seal was visible and it was letting water in and wetting the passenger side carpet real good. So I just got some sealant stuff and gunked it up all in there from both sides and it doesn't leak now.

Some times the fan is not running when the switch is on. Then it just starts up when it feels like it. If the passenger kicks the dash or if you go under the hood and hit the fan it starts up.
Those are the signs.

I don't know about your leak, jeepokee, but I get a leak in the cab when the A/C is on in the summer. My theory is that my sagging rear leafs are setting my XJ at an angle that does not fully drain the A/C condensation. I cheked the drain and it's clear. Maybe I am just over thinking it.

bmyohn, I probably could fix it if I hadn't ripped the **** out of it. I just wanted to open it up for fun.

The only thing you can unbolt is the A/C canister, and even then it won't move much. I just sqweezed it through the space provided. I've done this job on several XJs of differing ages. Patience and knowing it will fit through the cramped confines is key.

What do you mean by "whole case"? You'd have to remove most of your interior and take out the heater core to get anything else out.

Nice thread necromancy, by the way.

i have a 2001 XJ and my AC/Heat only works on setting 4 (highest one), since its both A/C and Heat iv come to the conclusion it has to be the fan, or some modulator or something like that. im not very mechanically inclined, im learning haha. but would you suggest i try this out? has anyone else had a problem similar to mine?

Try reading this thread. I'm sure it's just the resistor pack.
