Question about 2005 Chevrolet TrailBlazer

1 Answer

My husband started my 2005 trailblazer yesterday and the fan for defrost/ac/ etc was working fine. When I left for work it was not blowing anything. I put my hand by the window vent and could feel a little bit of warm air, but not blowing normally. We just checked the fuses and they are all fine (we think).

Check the blower motor resistor. mounted on the passanger side under the dash.its mounted right on the heater box with two screws. the last one i worked on the plug had melted and needed replacement. the replacement should be inexpensive

2005 chevy trailblazer ac won't work but defrost does while driving only


Hi. There happens to be a common problem with these trailblazers inside the ducting box located under the dashboard. The mode actuator door motor stops working due to a faulty motor itself and the default position is defrost only. As far as the Air Conditioning not working, there maybe another problem to diagnose there. Could be low refrigerant, or electrical problems to the compressor, or faulty fan clutch(another very common problem with these trucks). Type in mode actuator door and 2005 trailblazer in your search engine online i.e. Google or Yahoo and you will find many posts about this problem. I think there may even be a Youtube video about replacing it. Let me know you need more help. Thanks.

Make sure your fan is coming on, you should hear it come on when you turn on the A/C or defrost. The most common problem for that symptom is the fan relay burns out, and the A/C comes on strong but then overheats quickly making the pressure in the condenser get too high and the pressure cycling switch automatically turns off the A/C. The condenser then cools and the process starts over. If you can locate your radiator fan fuse and relay, which will be in the fuse box under the hood, you can rule out the relay by pulling one of the same size from another system that isn't important like the fog lamps(if equipped). As long as you verify that the fan is NOT working, you would try this relay swap test as long as the fuse is still good. I work for a Ford dealer as a technician, if you brought your vehicle in for service for an A/C or heater concern and your still having problems with it. You can bring it back in for a "recheck" or "repeat" repair and they will have no right to charge you again... If I worked on someones car, and the problem came back after they left, I would seriously want to know because I care about my work and care about my name as a master technician. Just remember, you do not have to pay for repeat repairs... EVER!!
I hope this info helps!~subyguru~

could be a fuse link. when you replaced the battery, did you put back all the wires ? fuse links are connected directly to the battery positive terminal.

check also the ignition switch, sounds like an accessory contact problem.

tnx 4 using fixya,
