Hi,
first problem may be not enough antifreeze or air stuck in the heater core.
Hearing water gurgle is a hint of air being where water should be.
I am not familiar with the 92, but it may be the heater control module, if it is electronic.
The blower motor may stop for many reasons, try jiggling the wires when it stops.
Could it just seize up mechanically?
Hope this helps a little. Take care, Eggert
