l have a 1993 GMC Jimmy.When l push the botton for it to go into 4 wheel drive the lights flash and then l hear a buzzing noise around the glove box. But it does not go into 4 wheel drive. I took it to a mechanic and he did a computer scan and said it was the actuator motor on the trasfer case. So we changed it and it still doesn't work.

What is wrong with it and how do I fix it?
Is there actually a problem with the actuator motor or is it something else?

Thanks,
Jack

What to check next

Diagnostic guidance. Suggested checks and possible repairs are separate from the owner's reported results.

Provide the existing scan results and any diagnostic findings recorded after the unsuccessful actuator replacement.

could it be a buzzing sound like a relay not working properly, or does it sound more like a door buzzer?

not saying that it is a door buzzer just trying to figure out what kind of sound it is.

Discussion summary

4 wheel drive

The owner of a 1993 GMC Jimmy reported flashing indicators and buzzing near the glove box when selecting four-wheel drive, without engagement. A mechanic attributed the problem to the transfer-case actuator after a scan, but replacing it did not restore operation.

Reported outcome: Four-wheel drive remained inoperative after the actuator replacement. No later resolution was reported.

The scan results were not supplied. A reply asked about the character of the buzzing; it did not establish a failed relay or another confirmed cause.
