yesterday I tried the onboard DTC and got these errors:

EO 33 OUTSIDE TEMP SENSOR
E0 35 OUTSIDE TEMP SENSOR
E0 73 HEAT SUPPLY UNIT COOLANT CIRC. PUMP
E0 75 COOLANT CIRCULATION PUMP

now where do IU find these items on my 93 300se??? and what exactly do these mean???
Am I in for alot of work???

oh and ever since I put in the new blower control regulator I have noticed that not alot of air is being blown out.. for ex.. on max you can hear the blower working pretty hard but the air that comes out of the vents doesnt seem adequate for the amount of noise... what could this be???

Thanks
