<!-- from fixya rte -->Where is ac blower relay on a 1996 suburban - 1996 Chevrolet Suburban

SOURCE: ac doesnt work

Check the grounding of the blower motor it's self. Gm had a small issue with the blower motor loosing it's ground. Run a test ground wire from the battery to the blower motor. If this doesn't help, replace motor.

If a/c compr engauges, with switch on, but just don't blow air, relay is ok, check voltage at blower motor with test light, blower motor is under dash on passenger side, if you have voltage there, replace blower motor assembly.

Yes, the motor may have a dead spot on the commutator. If going over a bump or hitting it makes it go, then replace the motor. I have pasted instructions below. Please let me know if you have more questions, and thanks for using FixYa.

REMOVAL & INSTALLATION
See Figure 1
The blower motor and fan is mounted in the bottom of the heater case. Depending on model and equipment, it may be possible to remove the blower without removing the heater case. If there is insufficient clearance below the case to get the motor and fan free, the case must be removed.

1. On Land Cruisers with the 1FZ-FE engine you may need to remove the right side scuff plate to gain access to the motor. Remove the linkage on the lower cover, then remove the cover while pushing the locking protrusion.
2. Disconnect the electrical harness from the blower motor.
3. Disconnect the ductwork from the casing if it will interfere with motor removal. The motor may have a smaller, flexible air exchange hose on it; remove it.

Fig. Fig. 1: The blower motor is mounted in the blower unit case. You should be able to see it from under the dash

1. Remove the blower motor fasteners and lower the blower motor out of the heater case.

1. Install the motor into the inlet duct. Be sure to position the motor so that the flexible tube can be attached to the motor and connect it. Install or connect any ductwork removed from the heater case.
2. Connect the electrical lead.
3. On the 1FZ-FE Land Cruisers, attach the lower cover, linkage and scuff plate.
4. Check the coolant level, add if necessary. Run the heater and check for any leaks.
