Recent issue.
Blower not turning on at all. This must mean the electric fan never comes on now..thats not too good.

Checked fuse under dash. - Good.
Just bought a circuit tester and going to check in the wire(s) to the electric fan soon to troubleshoot.

Looking for suggestions.
thanks. :)

P.S. the blower was not working from previous owner and then we replaced it.
Was working fine for couple months or whatever for the few times I have used it. few days ago problem started... Hope to find solution these Midwest winters get COLD :eek:

might wanna trace your power wire... could be an exposed wire is grounding out... IF you dont get it fixed I know you can buy a ceramic heater for your vehicle from harbor freight for pretty cheap

One common failure is the fan switch in the dash. See if you get power to the blower and if you don't, trace it to the ballast resistor on the heater housing under the glove box then to the switch.

Open connection maybe, grounding out would blow a fuse.

it might also be the connector to the dash-switch, located on the right hand side of the air-co/temp control unit.
this connector will sometimes loosen a bit due to rough-riding. everything will work fine except the blower..

Every time I see the title of this post I am reminded of the provision in the J. Howard Marshall / Anna Nicole Smith pre-marriage contract.

bwahahahaha nice one!
And thanks for the info all!

After the previous owner, the control unit has been replaced by a pretty sharp radiator place I have been to in the past and that shouldn't be an issue i wouldn't think.
So if that eliminates anything..

Speeds not operating in the blower is a common problem for TJ/XJ owners. Here is the stock resistor replacement write up. I do know people also put in relays for speeds 2, 3 and 4.

Here is a write up for the relays and the switch.
