Itswiggs Posted July 21 Report Share Posted July 21 2018 dodge journey gt 3.6 6 cylinder. Front of vehicle, blower works on every setting (still weaker than when it worked proper) except maybe half power on highest setting. Replaced blower and still same issue, this vehicle does not have a resistor equipped on the front of the vehicle. Replaced blower and resistor on back of vehicle and works fine. This is a 3 zone climate control hvac unit. Fuses and relays all check out. I have not removed and applied voltage to the relay outside of the fuse box to check if switch is operating properly inside of relay but if it was bad I’d like to think blower wouldn’t blow at all.

Dean H Posted July 23 Report Share Posted July 23 (edited) Check your cabin air filter. In the slot up above your blower motor. Edited July 23 by Dean H Itswiggs 1 Quote Link to comment Share on other sites More sharing options...
Dean H Posted July 26 Report Share Posted July 26 (edited) FYI, If your cabin filter is plugged up. Then you should check your engine air filter. It will be plugged up to. Mine was. Edited July 26 by Dean H Itswiggs 1 Quote Link to comment Share on other sites More sharing options...
Itswiggs Posted July 30 Author Report Share Posted July 30 Update on this. Still having the same issue however I recently purchased an obd 2 scanner and found u1190-00 + b1107-12. I replaced the sensors with ones off Amazon but still showing codes after cleared. Read on a different forum that not using mopar parts is the issue, so I will return and purchase oem and hope this will solve the issue Quote Link to comment Share on other sites More sharing options...
Itswiggs Posted July 31 Author Report Share Posted July 31 purchased humidity sensor from dealer and eliminated the u119-00 but they did not have the cabin air temp sensor in stock so need to wait for it. found it interesting that both cabin temp sensors (mopar and amazon) activate the "fan" on the sensor itself as soon as vehicle is powered on even without the hvac system on. it is used for the auto hvac setting and would like to think it would only turn on when this setting is engaged. the code states that there is a short b/w the sensor and the battery, this sensor as well as the sun sensor plug into the a/c and heater module then go on from there, so thinking that either its the sensor itself since either the mopar one is fried and amazon won't cut it, there is a short b/w the sensor and hvac module (because the sun sensor is operating normally) or the module itself has a short internally. when the auto setting is engaged the front hvac system cuts almost completely off with little to no air blowing whatsoever. will update when i can figure more out......

Mine was. i have replaced both just when doing random maintenance on the vehicle. cabin filter definitely needed replaced and put the hepa one in. i removed new filter while the blower was engaged and could definitely tell a difference when it was removed, now makes me think the hepa filter may be causing equipment to be overworked and cause it to fail sooner ultimately causing more harm than good.

Dean H Posted July 31 Report Share Posted July 31 For my cabin filter. I went low buck. HOME HVAC Natural Aire - Cut-To-Fit filter. 20" X 30" X 1" thick. Green one. Under $10.00 at Walmart. I should be able to get 8 or 9 filters out of it. It's more free flowing than a paper filter type. Works great. Itswiggs 1 Quote Link to comment Share on other sites More sharing options...
Itswiggs Posted July 31 Author Report Share Posted July 31 Honestly that’s genius. Never even thought to do something like that. Good way to save money and always keep a new filter in for cheap 🤦🏻 Quote Link to comment Share on other sites More sharing options...
