1995 Geo Prizm. A/C works and is properly charged but fan won't turn on. also speedometer doesn't work and longer.. any correlation?


blower fan in dash.
fan on RAD
fan in front of ac condenser in front of car.
does the fan in dash blow , on high?????????
does it? if not say so.

the car is Corolla,
and same car.
and works same.
when the Blower dies, in the dash , the A/C will be cut off fast.(but not if blower is dead)
this is normal for blower dead. (power to it, dead )
this is to prevent icing up of the evap core (might crack it)
SPEEDO SIDE TRACKED:
are both speedo and odom are dead?
why not say so/?


26232154-4g1iytzfkimywqjfw30jhjyb-3-0.jpg rule 2, if the dash blower blows on high , its not the resistor block
proof.
below.

on high the resistor block is bypassed,
if blower works and that center fuse below blows, the AC goes dead because 12v dont make it to the the clutch relay.
if top fuse below blows, a./c and blower die. even on high.
26232154-4g1iytzfkimywqjfw30jhjyb-3-1.jpg
you can see all this stuff on mitchell's, if you want. as most do.


btw , the a/c compressor may work , if the the blower has power, but the blower is burned out.
the A/C amp logic module sees the 12vdc leaving the switch and assumes the blower works.
this rule on blower on, is to keep the core from icing over, and that can bend things.
that resistor block is air cooled, and is on the fan chamber to get cooled that way, if not it burns up.
but why not tell us if the fan works on high.
that way we save 90% of all BS guessing.
why not?

first is fuses.
then if fan blows on high only, then the fan is ok and the resistor block is bad.
if blower dead on high, the blower is bad,
the fuse blown or the wires to it are bad or the switch,
what a tech does is use his voltmeter, a $10 tool.
if you have 12vdc to the motor then the fan is history, dead.
if not, 12vdc there, fan on, then you work them meter backwards until you find the open circuit.
really its that simple.
if confused ask quesitions.
if you cant test the fan on high, tell why?

Not sure which fan you mean. Engine cooling fan is different from heat/air blower fan.

Heater fan in 1991 Pontiac sunbird stopped working. We have replaced fuses, and the fan motor. Still not working, continues to blow the fuses. What to do?


Replace the blower motor resistor assembly. To locate the electrical connector for the blower motor resister, it is usually attached to a heating or air conditioning Duct, or the blower motor case. You can also trace the Purple Wire from the blower motor back to the resister. Also make sure that the blower fan is not jamed up with somthing in side and will spin freely,or binding same thing, this will also cause the fuse to blow right away. And does the motor actually spin a bit before it blows the fuse or does it blow the fuse at the same time the switch is turned on? Good Luck and have a good XMASS.
