I have a 2003 chevy venture that the medium fan setting does not work I have been told the resistor is located on the driver side and hard to get to . I am disabled on SSDI and would like to know how to replace it.

Thanks

Be sure to also leave the year, make, model and engine size.

That TrailBlazer is a 4.2L? Is it a V-6? My 2000 GMC has the 4.3L high output V-6 witch leads me to believe its a large bore 6.

@Michiganborn1969 ... 2001 was the last year for the 4.3 Trailblazer. The 4.2 is a 6 cylinder and they also offered the 5.3 8 cylinder.

will a blower motor from an olds alero fit on a pontiac sunfire?

[markjhicks]

@zach9802 I honestly have no idea. I suggest contacting a local salvage yard, they should know the answer.

Thanks Mark for the comment. I never learned to play base but they say if I really want to know how a song is played to try to listen to the base in the song. I've been playing on/off since 1991 but if I take out all the breaks where I didn't play it probably would amount to about 3 solid years lmao.

Cool, thanks Mark. I will see you tomorrow morning on the Podcast with. Eric & Rich.

@markjhicks Absolutely, Mark. The theory is what carries the day, ultimately....
