Have a problem with a/c wiring. blower motor runs on high all the time when you put the switch on max or normal air.i mean the blower is on high for max and drops down to highfan in normal position.just got car 1 month ago is a 92 rs 305 tbi.changed out the fan switch and had no change but had problem with elec control switch.had to push conector back on real hard.looked under hood and found jumper between the orange wire from the high blower relay and the lt. blue wire coming off the sensor on the condensing canister(a/c clutch cycling pressure switch) changed out the high blower relay and it made no change. without the jumper fan does not work.compresor runs radiator fan runs and i can hear vacum doors open and close but the blower wont work without jumper. any one have a clue?

 

sorry-its the lt. green wire coming off the condensing canister not the lt. blue wire.
