Saturn Repair Problems? Ask a Mechanic for Answers ASAP
Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.
Do you have power to the blower motor at any speeds or any time at all?
Let me know so we can continue,thanks Pete
There was no answer would you like me to call you back on this?
O.k.,so you want to continue here instead of the call is this correct?
O.k.,locate the 40 amp HVAC blower fuse in the under hood fuse panel.Double check to make sure it is o.k.If it is o.k. test and see if it has power at one terminal that this fuse seats into in the fuse panel ( at or near 12 volts DC) with the key on or off.If it does not have power let me know.
If it does have power but you have no power at the blower motor then this indicates there is a broken wire leading from this fuse to the blower motor.This fuse feeds direct to the blower motor to give it power at all times.
O.k.,It is an orange wire all the way from the fuse to the blower motor.
You have power at the blower with the switch off but not when it is on?Are you testing with a test light or multi meter?
What does the voltage read with blower switch off and then when the blower switch is switched on?
Is this testing with the ground lead from the meter connected to a good ground point and if so have you tried with the ground lead connected to a different ground point to see if the voltage readings change at all with the fan switch on and off?
O.k.,you are losing voltage off this fuse.Now does the fuse drop the voltage as well when the blower is switched on?
O.k.,so you are losing voltage on the orange wire from the fuse to the blower.This is due to a loose terminal connection at the fuse under the fuse box or corrosion in the fuse box or a corroded or damaged wire leading from the fuse to the blower motor.This is the only reason the voltage would drop/become lost like this here.
Correct.I am not sure if you saw my last post so I will post it again:
Did you see any wiring damage anywhere?
It is losing voltage so there has to be a break or damaged or corrosion in the wiring.
Let me know if you find anything.
