I have searched thru 7 pages of old threads with no useful answer. I have a 2001 Blazer 2d LS 4.3l. Reverse lights aren't working. I was told that I need to change out the Reverse light Switch. I ordered the part from Autozone. Any idea on exact location or have a diagram of where it is Located? I have looked online and nothing. I know people have said it is on the Trans but didnt know exactly where or it wasn't clear. Thanks in advance- JB

 

Auto or manual transmission?

Auto (#3):

Manual (#25):


For the auto trans, you need to adjust the switch so that the engine starts in park and in neutral.

 

OMG U are AWESOME! It is a Manual Tranny

And what number on your diagram am I looking for ?

 

As stated in my post above, #25.

 

I am having the same problem with a 99 manual transmission but I can't get your link to work. Could you repost it for me? Thanks!

 

Pics not visible?!

 

That's what happens when a website like compnine takes down their service. Someone will have to find that information for you again when they have time. I did not keep those images, only linked to them so I do not have a copy, nor do I have the time to do the searching any longer. Good luck.

 

Found a written description.
Thanks

 

Hi all my Blazer brothers! i have a 2001 Blazer LS automatic trans 4x4. when i bought the truck from the guy he told he had taken out the reverse bulbs because they wouldn't turn off. so for the heck of it one day i put them back in and wallah they were working fine. i just went to the car wash and when i was done washing it i noticed they were on again and the truck wasn't even running so i took the bulbs back out and came inside to post this message. anyone have any ideas what might be my problem.(how to get them to turn off or what i need to replace?) Thanks for your time and your help!

 

Well since I was having issues a little farther up i'll give you an update of what i've done. I found the switch, of course it's a little hard to get your hand up there.....but then again I got kinda big hands lol. Anyways I jumped past the switch to prove that was the problem and the lights come on. Well I was none to interested in trying my luck to get that old switch out because I didn't want to risk ripping the threads out of the old casing; the metal is starting to show it's age. Anyways I hooked up aux rev lights.....stock was never enough and ran them to a switch on my dash. Yea it's a little extra foolin but it works.

BlazerLS: It sounds to me like your missing some insulation on the same switch I have broken and when water gets up there it's causing a ground a lets the current flow past the switch, turning on the lights!
