Our 1997 Blazer with 98K miles, has been very reliable, although not without
"issues". No problems until we hit about 65K:
* A/C Compressor Replacement
* Alternator Replacement
* Rear Wiper Motor Replacement
* Thermostat Replacement
* Front Differential Seal Seeping Oil (recent)
* Tires/ Brake Pads (same rotors), Shocks & a Battery
Other than the above, there have been no problems since new. The truck has
never failed to start & get us where we wanted to go. The drivetrain
components, engine, auto transmission, X-fer case, etc. have been bulletproof.
Prior to this vehicle, we had a 1984 S-10 Blazer (2.8L) that we put just over
250,000 miles on without any major component replacements required. The truck
was retired for reasons related to RUST damage from all the Northest
winters...there were no drivetrain issues & it still ran well. Hence, the
purchase of the '97. Good luck with whatever you buy.
