Replying to: steveo16 (Aug 13, 2009 6:37 pm) about your problem. I will let you know what he says. I tell you, I have never seen so much electrical problems on these Blazers and Jimmys in my life. GM has 43 technical service bullitens on them and several recalls. I'll be back... Thanks for your patience...

Replying to: cardoc50 (Aug 14, 2009 3:20 am) I know there were major electrical issues with the 2nd generation when it came out. Sometime during this generation there were some major improvements made in the harness designs that helped. But these are still one of the early generations that had a BIG increase in complexity. You want to see one that will really mess with your head? Check the door jamb switches. On my '02 2dr, there are no wires to them! The BCM has a remote sensor/switch inside the door that reads the latch, and turns on/off the interior lights accordingly. Bizarre.

Replying to: jlflemmons (Aug 14, 2009 7:24 am) would they put that in the door to turn off the interior lamps? I thought the switch was fine. It worked for 50 or so years! LOL. I'm going to the Ford store and trade mine in on a new Fusion. lol

I need help. My 1997 Jimmy 4x4SLE will only start when you release the key. I crank the engine and it cranks normal but will not start until you release the key. That means most of the time it won't start because you only have a second before the key is on the on position. Of course the first thing I thought of is the ignition switch. It has the high output csefi engine or OBD 11 as it's called. Remember it is a 1997 year model. My question is simple...Where is the actual ignition switch on my model? I know this will sound stupid to a lot of you guys but,stupid is as stupid does! lol. Please help.The Jimmy looks brand new and I've kept it that way. I want to drive it again. I've even let the registration run out.(no tags) Now it just sits in one side of my garage looking pretty. If you think it's not the switch, I'll surely take any idea and look into it. "WHERE IS MY IGNITION SWITCH?" and to think I'm a retired mechanic with 38 yearts of service! I'm anxiosly waiting for a reply.Thank you so very much.

Replying to: jlflemmons (Aug 21, 2009 11:59 am) My Jimmy's the year where you use a screwdriver to bend the spring away from 4 notches and then remove the horn (airbag). then I can get to the steering wheel and then the switch. Guess what the switch cost? I may have you send me some money! LOL 17.69. Seventeen dollars and change. Thanks friend. I'll let you know how it goes. I also heard it was a common problem on those vehicles.Thanks again

Replying to: cardoc50 (Aug 23, 2009 7:16 am) regarding the switch, you're luck you are changing the cheap switch in the column. You don't even want to know what that multifunction switch on the left costs! Would you believe $195 wholesale???!!! And on a 2002 model, $265 wholesale!!! Needless to say, if anyone drives my Blazer and doesn't treat the switch with gentleness, I thwack them in the side of the head.

Replying to: jlflemmons (Aug 23, 2009 8:39 pm) Well,I had to change the multifunction switch over 2 years ago. Did'nt have any rear lamps. The 17 dollar switch I was reffering to was just the key switch.Come to find out the ignition switch directly under the key switch is 99.00.So I cleaned and tested the ignition switch and it is fine. I put the column back together and drove it for about an hour and everything seemed fine.I think I'll put license back on it and drive it again. My 99 cavalier is ok to drive but, it ain't no Jimmy! Thanks again for your help and concern. You are a good man. TTYL
