New to this site, so here is my first question.

My speedometer is out, how should i check it? thanks for your time in answering, I just think this website is great, I am learning so much about my blazer its very much exciting.

Radar or GPS???

Have you checked your speedo cable? I would check that first.

I thought 97 S-10's have an output speed sensor at the back of the transfer case on a 4x4? If the check engine light is not on for a speed sensor code, and you can check with a scan tool that MPH is registering, then the problem is probably in the cluster.

You are probably right, I haven't worked on an S10 in a while.

If it is the gauge cluster it would work. Do you have an OBDII that can read the signal from the speedometer sensor?

no i have a code reader its a MAXISCAN MS300 Code reader

I think you can just swap the cluster. Just make sure the one you get comes from a vehicle with the same trans (manual or auto). I think the manual trans clusters had the PRNDL omitted.

Did you get it resolved or are you still working on it?

I am working on it, will let you know what I found out, I am learning all I can about my blazer and let me tell you, theres a lot to learn, also have to give bigytwotone kudos, as he and his dad have been helping me with my blazer as well, very much appreciated.

On Friday, I compared the GPS to the Speedometer and it is registering the same speed on both. It is working fine, now just need to find out why I am burning Rad fluid so quickly, that is my next issue.

On my 98 S-10 the intake manifold gasket started leaking and caused it to almost drink anti freeze before I replaced it. It was leaking right under where the AC compressor mounts and running down the front of the motor while it was running. I've heard of it leaking to the inside of the motor and destroying it but I was fortunate. Can you smell hot anti freeze while the vehicle is running? Have you checked your oil to see if it looks like it should? The other place to look is the weep hole on the water pump, usually it will leave a puddle when it's parked.

Her truck is burning the antifrezz so she is not that lucky so we are ordering the parts and she has stoped driving the truck
