I have very bad news. The blower motor in my 1992 240 quit. It's been making some ugly noises for a while now, so it's not too surprising. However it occurred to me that it's a royal pain to replace heating components, what with dash removal. What should I replace? Blower motor or the resistor or both? I really don't wish to have a mechanic do it because i'll have to pay as much, if not that than more than the car is worth. Anybody know about replacing these things? Perhaps I could do it as a long term project with my father who has also helped me work on the car. Another reason this is disappointing is I just bought about $700 worth of A.C parts. I would like to fix it but need to know more about it I guess, and what you'd recommend. It's quite possible I may have to sell it.
Anything would be great!
Thanks,
Evan Piveral

 

well, the resistor can easily be tested with a multimeter in 'ohms' mode... but even if the resistor is totally fried, the motor should still work on high (the resistor is used for the slower speeds).

there's supposedly an easier way of replacing 240 blowers via the 'chain saw method', where you cut a hole in the side of the airbox the blower is inside of, and swap it via that hole. I've not attempted this.


here's the 'straight' way of doing it...

and another full dash disassembly on a newer version

and here's the chainsaw method without pics
In a 240, there are two ways to replace the blower motor -- the proper way, and the butcher's way

darn it, somewhere I saw a complete pictorial how-to on the chainsaw method and I'm just not finding it now. :-/

 

Thanks. Just out of curiosity, there aren't much differences between the 1990 and 1992 240s when it comes to this is there?

 

nah, the changes year to year were mostly pretty small. somewhere around 92 or 93, they changed the heater controls and heater valve, but they retrofit the new style heater valve onto the older style cars as a replacement part.

if you see stuff referring to that copper coil thermostat, you likely don't have that, and can ignore it.

 

Got the blower motor and a few other things fixed! I'm happily reunited with my car.

 

Happy living! :-)
