1996 Sonoma heater blower not working. I replaced the motor but still does not work

SOURCE: Blower Motor Resistor for front AC/Heater

remove glove box....its in the casing near motor.....2 screws and 1 connector

SOURCE: Blower motor or resistor?

Yes its the blower motor resistor.

More then likley theres some trash or something in it, or possibly the motor itself is on it's way out. There not that bad to pull out of that body car, just pull it out and see what you can see.

The blower motor is under the glove compartment

You can replace the resistor on your own. Please find a detailed diagram which would guide you to do it.

Removal & Installation
2-Wheel Drive - 2.2L Engine

1. Remove or disconnect the following:
   Negative battery cable Front exhaust pipe, if necessary for access Starter heat shield, if equipped Brace rod from the front of the engine and the bell housing Drivers side wheel to access the starter motor wires and the starter motor attaching bracket-to-engine bolt through the opening in the wheel well Wires from the starter solenoid Attaching bracket-to-engine mount bolt Starter-to-engine block bolts. When removing the last bolt, be sure to support the starter to keep it from falling and possibly injuring you. Starter and shims (if equipped) from the vehicle Bracket from the starter assembly, if equipped

1. Install or connect the following:
   Bracket to the starter, if removed. Tighten the bracket nuts to 97 inch lbs. (11 Nm). Starter and shims (if equipped) into position in the vehicle and thread one of the retaining bolts to hold it in position. Bracket-to-engine mount bolt (loosely), if equipped Starter mounting bolt, then tighten all mounting fasteners to 32 ft. lbs. (43 Nm) Wiring to the solenoid Brace rod and tighten the retainers Front exhaust pipe and tighten the fasteners, if removed Starter heat shield, if equipped Driver-s side wheel, if removed Negative battery cable

Hi!
To find out if your problem is the blower motor or the blower resistor or switch perform the following tests.
BLOWER RESISTOR

• Remove resistor from vehicle or disconnect resistor wiring.
• Using an ohmmeter, ensure continuity exists between blower resistor terminals No. 1 and 4. See Fig.
• If continuity is not as specified, replace resistor.

1. OFF (1)
2. LO 5 & 6
3. (D) (2) 1, 5 & 6
4. (D) (3) 2, 5 & 6
5. HI 5, 6 & 8

• Remove heater relay.
• Using an ohmmeter, ensure continuity exists between heater relay terminals No. 1 and 3, and between terminals No. 2 and 4.
• Ensure continuity does not exist between terminals No. 4 and 5. If continuity is not as specified, replace relay.
• Ground terminal No. 3, and apply battery voltage to terminal No. 1. Ensure continuity exists between terminals No. 4 and 5.
• If continuity is not as specified, replace relay.

1. Disconnect negative battery cable.
2. Remove glove box, if necessary.
3. Disconnect blower motor and resistor connectors.
4. Remove 3 screws and blower motor.
5. To install, reverse removal procedure. See Fig.
