I've searched the 'search button', there was one visual reference, but my engine bay does not look like that at all. or maybe i can't find it in my engine. Here is what my engine looks like, 98 blazer.



purple = is that the relay??
red = what is this thing? a filter for something??
light blue = is this area where the blower motor parts are? switch, relay, resistor?? etc etc



i wasn't sure, but is this it right here?? the blower motor?? but where is the relay and resisitor??

if it helps any, my problem started happening when i went through the carwash, so i'm thinking maybe the water did something to it, thanks for any help!

 

Purple is the relay.
At the edge of the purple, just into the light blue is the blower resistor. Inside the light blue area is the evaporator core.
The can in the red is the accumulator (drier)

If you put your vehicle into the post or your sig it would be helpful. I'm assuming this is a '97

 

Rob's got it right.

Well, all except for the year. It says '98 right up in the first sentance!!! LOL

Anyway, it does help us out greatly if you put your vehicle information in your signature. Keeps us from having to hunt it down even if it is in the post somewhere.

 

thank you all! 3 more quick questions.

1. how would someone replace the relay?

2. where is the blower motor switch?

3. and where is that darn motor blower? do i have to take off that plastic cover? that's circled in light blue (see my picture)

thank you. thank you. thank you. =)

 

To replace the relay, just pull off the electrical connector and the relay is either held on with a small screw or a plastic tab.
The blower motor switch is in the dash on the a/c control head.
The blower motor is circled in red in your second picture. To replace the blower motor you have to move the VCM out of the way, remove the coolant resevoir and cut thru the rubber to get to the mounting screws for the blower motor.

What is the problem you are experiencing....no air from the blower?

not work in position 4, 0-3 works fine. I searched the searched button and came up with the relay that needs replacing, hopefully it is the relay!

thanks for all the replies! ^_^

 

Sounds like a good diagnosis, let us know.

 

I have no heat or a/c how can I check the blower motor switch.
