You'll need a 1/4 in drive set, Phillips and flat screwdriver, drop-light, and patients. Last time I removed and replaced the dash on my 97 I only had three screws left over. That's a personal best for me. Good luck

When I did my 2000 Blazer, I followed the Haynes manual. It wasn't perfect, but it had 90% of what I had to do. The dash, while somewhat intimidating, wasn't that bad. For me there was a piece under the dash that had to come out in order to get the heater core out. It took me hours to finally find the 2 studs that were poking through the firewall. I had to remove the right front tire and go in through the wheel well to get to them. If I had had good direction this would have been minor, but as I said, I lost hours just trying to locate these on the engine side of the firewall.
 
Good luck

I have a 99 S10 with the same problem. Did you ever get a solution?
 
Thanks

when the control is to cool, there is warm air coming out of the floor vent, if the a/c is on max its cool coming out of the dash, not cold. whats to be checked? please advise.

The first part is normal for the S-10, just put on the dash vents. With the A/C running, feel the large line at the compressor, is it cold.

The large line at the compressor should be cold not cool, I would think you are low on 134a. It should be checked by a pro, the right way to fill a 134a system is recover and then add the factory amount back. I would say a leak check should be done also.

95 S-10 I turn the heater on and the P brake light comes on by sn4ck0

95 S-10, I turn the heater on and the P brake light comes on, and the speedometer goes to Zero, Fuses are ok, every once in a very rare time, I would turn it on, and every thing works fine, but as I'd turn it back off, it'd maybe come back on once (some times it won't), then it won't work properly after that for ages.
 
I had read somewhere that it may be a Ground near the Dash Cluster, but I've no Idea where the Dash cluster is at, I've the repair manual as I've had to do many repairs to it, and in the Electrical Diagrams area, they list quite many, many grounds, many more than what I wish to check, I've check and cleaned the grounds in the engine compartment, all are swell.
 
Any Ideas?
 
Thanks in Advance.

Your gauges are your dash cluster.Look under the dash for grounds.
