1996 olds 98. the blower motor is stuck on defrost and floor.all the buttons light up when pressed. it does change from hot/cold.

How did you test the A/C system ? Hook up gauge manifold , test A/C pressures ? Manual or automatic climate control ? The blower motor only working on high means the blower motor resistor is bad ! Did you hook up a scan tool an check high an low pressure switchs inputs to the PCM - engine computer . Does the A/C compressor clutch engage ? turning on the compressor ? Moving the mode switch does nothing . Doesn't move from floor to vent to defrost ? Probably the mode door actuator ! Don't think the HVAC control panel is bad . Just a few little things . Pushing the A/C button on the control panel just send a electrical signal to the PCM , the PCM will energize the A/C clutch relay , turning on the compressor .

Heater Blower Motor Troubleshooting

A/C Switch Assembly
The A/C switch assembly integrates the A/C request button, RECIRC request button and rear DEFOG button into a single assembly.
The A/C request button is enabled by the blower motor switch. The A/C switch assembly sends a reference signal to the blower motor switch. When the reference signal is grounded (blower motor switch turned ON) the A/C request button is enabled. The A/C request button is disabled when the blower motor switch is in the OFF position. When the A/C request button is activated (indicator ON), an A/C request signal is sent to the PCM. The A/C request button indicator can be toggled on and off when in the FLOOR/DEFROST or DEFROST mode, but an A/C request signal will be sent to the PCM regardless of the indicator status.
When the RECIRC request button is activated (indicator ON), the air inlet mode door actuator will drive to the recirculated air inlet position. When the RECIRC request button is deactivated (indicator OFF), the air inlet mode door actuator will drive to the fresh air inlet position. The RECIRC request button is disabled when in the FLOOR/DEFROST or DEFROST mode.

vacuum controls stuck work the knob a bit and try to free it..

Does it sound like the noise the turn signal makes? Does the noise change if you change the speed of the blower motor? Do all the function of the heater work (defrost, vent, floor, recirculate, fresh air, hot, cold)?

International 9400 9200 9900 heat box is under the passages side seat. That where the heater core location and the ac evaporator blower. You have two control motors under there one control the bunk for hot and cold. The other control front for hot and cold. Defrost vent and front vent is in the dash. My suck on defrost and in floor will open to front vent. I have not locate yet.

Temp blend door actuator possibly .

There is 3 actuators. One of them controls how much outside air gets mixed in with it.
The other controls how much hot/cold air is mixed, and one that directs the air. Floor to defrost. Which one was you looking at? The one that go's from floor to defrost is closest to driver side, under dash. The one that controls hot and cold is about in the center at the bottom of the ductwork. And the outside air is before the blower.

I would say that it is the mixer one. You say you can see it moving freely? I know in my truck, the stem broke loose from the flap inside the duct work. It would just blow hot air though. And lots of it. Or it would go to freezing cold. And get stuck there. Whenever I tried to turn it down a little.

Take the screws out of the bottom ductwork. That is the big vent comming from the blower over to the driver side. And check it out. Could have something stuck, Ink pen or something. And make sure actuator go's both directions and shuts off. I seen them get stuck trying to turn in one direction until it hits a switch and stops.

Good Luck.

It sounds like you have a blend air door stuck. This is in the housing of the heater a/c blower unit under the passenger side of the dash. There is a motor on the top of the housing that could possibly be stuck or on working.

will the air flow switch from floor to the mid to defrost? if so then we have a problem with the tempature door actuator. easy to replace just in tight place. Keep me posted for more help or if this was any help thanks
