A blown fuse can make your dashboard lights to not work in your 1993 Chevy Blazer Tahoe. A burned out bulb can also cause this.
my chevy blazer 1984 the air conditioner blows from down side only.
Chevrolet replaced the blazer in 1995 with the Tahoe http://en.wikipedia.org/wiki/Chevrolet_Tahoe
yes it will
They both use the 4L60E.

Generally you would need to have a replacement alternator which is only around $60 and it is refurbished but a 1999 Chevy Tahoe alternator should work just as well
its in the gas tank..you have to drop the tank to get to it!!!
It has a chain and not a belt. No maintenance required.
In 91 the Tahoe was based on the S-10 so no they will not work. The fullsize SUV was labled a blazer but it was based on the previous platform so no they will not work with the later C/K platform.
