Blower Motor Fan Speed Problems 900 1995

I am having trouble with a 95 960's ACC Blower motor-- There is no longer a 5th speed. If I step through the fan speeds position 4 and position 5 are now the same speed...there used to be a considerable difference in both sound and volume of air moved. When control is set to AUT, the max the fan will blow is equivalent to postion 4. No problems with positions 1 through 4. What could be the problem? Fan Resistor pack? Thanks...

    I think the highest speed is accomplished by having a relay connect the 12 volts directly to the motor. Probably the relay has failed.

    i think on some 960s the climate ecu controls fan speed and on others a seperate module mounted above and to the left of the fan on the air housing controls it. have yoiu checked the fan switch itself to see if it works properly?
