I was driving my new-to-me 98 Trooper and the blower unexpectedly stopped working. I checked the fuses, and everything looked fine. Does anyone have any ideas or tips? Thanks! John |
replace the blower motor and resistors. its a common problem withthese things
|
Thanks. Is the blower pretty easy to get to? What is the cost? I had something similar happen in another car, but it gave some warning at least. Still hoping there is some other electrical fix that isn't blower related. Thanks John |
the reisitor is not common on the trooper but the brushs in the motor will stick, tap on the motor and see if it will work
|
This may seem like a dumb question, but which one (of the two very similar looking black boxes behind the glovebox) is the blower motor? Both appear to be part of the HVAC system. Thanks! John |
Check for 12 V at the blower plug.Edited by: atfdmike

If you ck for power, as long as the fuse is not blown it will have power, the resistor is on the ground side of the circuit, the blower motor is on the far right has a 2 wire connector going into it, its next to the kick panel

Finally had time to test everything this weekend per the info others have posted above. I removed the blower and checked for voltage at the plug. I got good voltage on the plug. I also tested the blower motor via direct voltage from the battery, and I confirmed that the blower would work with power supplied (although it didn't spin immediately once power was supplied?). Something I noted that seemed strange was that the voltage on the plug didn't seem dependant on the switch position. Could this be lending itselfto a bad switch or is there something else that could be wrong? Thanks! JA |
