In my 1999 Quest the front blower (heat, AC, ventilation) does not work at swich positions 1 - 3, but works at 4 (full speed). In 2001 Hynes repair manual, on page 12-59, I located the likely problem spot: the "front blower motor resistor" block has 3 resistors and a fuse. If the fuse blows, this would cause the problem I see.
But where the "front blower motor resistor" block is physically located in the van, I don't know.
Will appreciate any suggestions.
Thanks, Mike
