So your saying that the blower motor will not blow anything hot or cold.

You probably need a new blower motor . Its not likely that all speeds would go especially high speed since all the other speeds go threw a resistor and high speed is direct B+ from the battery. Start therebefore I have you testing a/c parts. Keep me posted.

My heater is stuck on and blows extremely hot air at all times, harder and hotter once it has warmed and is being driven. Though, never off at any time.


it would appear that you will have to replace all items damaged during the theft attempt
as all the items are part of the dash assembly including the radio, I would consider a complete dash from the wreckers and that way you only have to hook up the wiring harness connections

95 honda passport heater does not work. Fan turns on but no heat. No clue what it could be. I noticed the problem after I had a radio installed and the automatic transmission rebuilt.


May be in the radio installation. I hate pointing fingers at the last guy who worked on stuff, but they could have hit a blend door.

When car is warmed up, turn heat on vent and like 3/4 power for fan. Turn temp knob from hot to cold. You are looking for a temperature change. Now, turn on a/c to vent. Wait for it to blow cold. Turn temp knob to hot. Looking for air to be warmer that it was. POST RESULTS

Air conditioner


Check whether the warm air isn't going in with the cold air .Coolant line that runs into the firewall on the passenger side of the engine which is toward the bottom half of the firewall on the passenger side. If there is warm air going into the vents with the cold air then it blows warm air. You may have to shut it manually because it gets stuck sometime. Check it out.

Air conditioner turns on when car starts.


If only the AC indicator light is on but you are still getting warm air from the vents, this is not an issue.  Most newer cars run the AC compressor nearly all the time to prevent moisture accumulation inside the car.  Without the compressor running, your windows may steam up and hinder your visibility.

2002 Nissan Altima - Heat doesn't get hot and doors get stuck


Did the switch break because it was stuck? If so, then yes, they will have to change actuators and doors. Does the fan work on all speed setting? If so then you do not need a blower resistor. The resistor pack only controls the current flow to change speeds of the fan.
