Faults:
First I want to address a couple of issues I read about in other 1998 Blazer reviews. First, windshield wipers intermittent, or not working when it rains, can be caused by the solder joints cracking on the circuit board inside the wiper motor assembly. A few minutes with a soldering iron can fix this. The main wiring connector attaches to the plug on the circuit board and these are the ones that come loose. That may be why wiggling the wiring makes it work for a while. This is also true with several other GM models. I have done this twice on this Blazer.
Second, the manual seat recliner handles break and there is an after market handle that you buy to fix this. Performed this repair on the passenger side only, driver's is electric.
The expensive fuel pump repair is especially annoying. There is no access to the top of the fuel tank and it must be removed in order to change. Lots of labor and an expensive part.
Two fuel pumps, water pump, oil lines, transmission oil lines, front and rear brake rotors, air conditioning, side mirror adjustment switch.
Now the heater/air conditioning alternates from heat to cold, like the heater control is bad.
General Comments:
Ride and comfort: the ride is like a small truck, rough with a lot of shaking front to back, probably caused by the short wheelbase.
Very small area for drivers feet, my legs cramp up after 150 miles or so.
Good points: with snow tires, this vehicle has gotten us through several bad winters and never got stuck.
Four wheel drive has worked fine.
