Testing The Blower Motor

After speaking to Jon Delucia at jeepair.com, he verified our suspicion that the blower motor was drawing too much power. A new blower motor shouldn’t draw any more than 15 amps on High. A worn motor that might cause problems will draw 20 amps or more on High. If you test yours and it is pulling more than 20 amps it is likely time to replace the motor. Fortunately, the blower motor on the TJ is much easier to get to than any of its short-wheelbase ancestors. Simply remove the computer and battery and it comes out by removing just three bolts.
