Hi!!

\015\012Blower motor in this vehicle contains an electronic circuit breaker (ECB) which resistance inreases if motor overheats and cuts power to motor. Motor's ECB resets as soon as power is cut to unit and moror cools down.

\015\012Your blower motor may be going out, which is not rare after 18 yrs or service. Replace motor and your problem will likely be solved. Part of the a/c circuit is shared w/power door and parking brake light circuits.
