For some reason I cannot find the relay that control's the blower motor. I have checked the motor directly on the batterie and that seems to work fine. The blue wire coming from the relay does not get any juice.

For some reason I cannot find the relay. Can anyone tell me??

Thanks,

 

under the hood passanger side if u look right under the cowl assambly u will see 5 wires sticking out of a connector the resistor is the thing behind that in the firewall.

 

So if I stand in front of the engine, it is on the right separatetely from the actual fuse box??

 

I just checked and I do see a connection block on the side of the blower motor under the hood. However, the wires are not having the actual colors as they should be. (Blue, black-orange, black)

Any ideas or am I looking at the wrong wire?

 

its called a resistor not a relay btw
here is a pic and the removal set by step
REMOVAL[*]Open hood.[*]Locate and remove the wire connector from the blower resistor block. Block is located at the back of the engine compartment on the passenger side of the vehicle under the wiper module Resistor Block Removal NOTE: It is not necessary to remove the wiper module to access the resistor block. WARNING: The resistor block may be hot. Do not attempt to service the resistor block if the system has been running recently. Let the system cool down before repairs are initiated. [*]Remove resistor block by inserting a flat blade pry tool on the side of the resistor block and pushing inward. Two guide lines are shown on the right hand edge of the resistor block to help guide the blade position. This will release the clips on the side of the resistor block. Pull resistor block out.

Thanks for the input. I normally go by the Haynes manual and have done lots of work on this van. I just got lost by the wiring of this problem. According to Haynes, the blower motor goes to the PDC under the hood where a relay is located. That is teh reason whay I got confused because when I removed the PDC, there are no wires in those colors and no relays that confirm the blower motor.

If I am correct, the resistorcontrols the speed of the blower motor. If I replace the blue wire with a powered wire, the blower motor runs, including different speeds. So why would the resistor be bad?

Just guessing here but it seems strange to me.....

 

does the blower motor run only on high? if yes then yes u need a resistor. The resistor is just a way of currant control 12 volts are alwase there and if u have 5 volts going to the blower motor then u get a slower speed u have 4 resistors inside the one resistor pack u will see it when u pull it out.

 

The blower motor does not run at all. However, if I change the blue wire towards the blower motor with a wire from the batterie, it runs, even with the controls.

So the resistor works. I just don't get juice on the blue wire towards the blower motor......

 

check fuse 21 40 amp in the pdc<fuse box>

 

Fuse seems to be ok. No. 21 is normally the location of the 1998 models though.....
