a/c blower issues
 

hello all i have spent some time lately working on my a/c system 1996 seville sls i have some tips if anyone runs into issues

What kind of tips do u have? I am having aproblem with mine. It has passenger and driver contros. So even if I have it with passenger off and control it from driver the passenger side blows ice and the driver side just blows air. Any idea what it may be?

ac issues
 

first question is: on mine the passenger controls refer to the back seat passengers. if that is what you are refering to...you have air blowing out of the rear vents but not out of the main dash vents then your blower motor in the engine compartment wall has gone out (this could simply be a bad motor or it could be the relay)

if you have controls that seperate the driver side vents and the front passenger vents then it is likely a vacuum leak.

clarify that for me and i think i can help you trouble shoot...my passenger (rear blower and vents were working fine, it was my main blower motor that blew. even though the rear blower motor was fine, and yes there are two)

ac issues
 

sorry i just caught that you have air blowing from all vents but only cold from one side.....if i got that right and you have dual climate controls (one temp for front right passenger vents and one temp for driver side vent) then the problem is in the controls. if this is the case i think your only two possible issue would be a malfunctioning a/c heater control unit ( this is the brains/computer that runs the system on my seville it is located behind the glove box on the upper fire wall inside the cabin, they dont make these new anymore for older models like my 96 seville, the issue could be the climate control switch itself.......i could use more detail info if you would like me to help you troubleshoot

u have a bad actuator , one side not moving

Yes it is my front vents where is the actuator motor located

Is it a blend door actuator or am I wrong

Where is it located and how much is the part

driver side not working . back by gas pedal in centre look up and u should see the part
