That used blower motor might be bad.
The resistor might also be bad.

Usually when one goes bad the other does to.

 

when i try manually before put it in it works strong atfirst
or what is resistor ? 4 pins little box? any pepboy or strauss got them? to replace
thanks again

Those links bring you to a site. One pic is of the resistor and the other link is to parts.
Your resistor might not also look exactly like that one.

But it is to the left of the blower motor.

Keep an EYE on the blower motor. Usually the Resistor goes bad first and burns up the motor.
The motor I will bet is weak as well.

 

hi tech again
it was my resistor bad Tech soon i got the R replaced it works pretty good
thanks tech for helping
and could you refer me to the " Cruise control " troubleshooting
mine cruise control not work... i was looking for checking cruise control system
thanks in advance

 

The cruise control pump is mounted to the bottom of the battery tray.
Check all the hoses coming off the pump really good.

 

any indicate light shows on dash instrument board when the the cruise switch on is engaged ?
mine i didn't see anything shown or the turning signal switch is bad.. thanks again

 

No light to say it is on.
