The other rule about replacing blower motors is that the large, weirdly delicate plastic assembly containing the motor and fan that is easy to yank out can be nearly impossible to put back. The vents, tubes and wires snaking out from it in multiple directions must connect simultaneously with the precision only the robot that built your car can achieve.
Here’s a secret that I’ve learned after replacing two blower motors: When automakers assemble a vehicle, the first part placed on the assembly line is the blower motor — then they build the rest of the vehicle around it. Thus, a $50 replacement blower motor (that will start to squeal when your car is only about five years old) will require disassembling half the car and $1,000, $2,000 or more in labour costs to fix.

I was pondering that last week while trying to replace the blower motor in our Nissan X-Trail and crying quietly to myself while surrounded by assorted pieces of dashboard, wires and electronic components of mysterious function. (You’d think I would have learned from spending an entire weekend many years ago replacing the blower motor in our second-hand Volvo 240 that some things should be left to professionals — even if it costs a lot.)
