This issue is on my 97. When I turn on the Defrost+Floor vents w/ heat, after 15-20 minutes or so it will start blowing very weak until I switch it to Front Vent, wait for it to start blowing, then back over to the Defrost+Floor Vent and then it will go back to normal. I will usually move around the temp if it gets too hot and it might be a trigger for this weak blowing, but I don't know. This seemed to have just happened a few days ago when it started getting cold. The blower motor is working, I can hear it moving like normal. It doesn't seem to have a problem with the front vents, as it blows just fine. Is this something as simple as lubing up the actuator links? I will check the coolant to see if that's triggering it, but I do have hot heat, so I wouldn't think that it would be an issue.
Kinda weird why its acting up now, last fall it didn't do this, it stayed on the Defrost+Floor Vent the whole time I was in the truck in the winter, no issues.
