The heater core under the right side of the dashboard may leak engine coolant which can puddle on the passenger front floor. The loss of coolant may cause an engine overheating condition. Our technicians tell us that removal of the dash board is necessary to replace the heater on these vehicles.

Chevrolet S10 Blazer Problems
Power Window Motor May Fail
Electrical & Lights --
Verified
A door window may move slowly or stop in mid travel due to a failing power window motor. The affected window may start working again after the motor cools off. Replacing the faulty window motor will commonly correct this concern.
The Fuel Pump May Fail Causing the Engine to Stall or Crank Over But Not Start
Engine --
Verified
The fuel pump may fail causing the engine to stall and not restart. Our technicians recommend replacing the fuel filter every 30,000 miles to help prevent undue strain on the fuel pump.
Transmission Output Seal May Leak Fluid
Drive Train --
Verified
The transmission output shaft seal may leak transmission fluid. On 2WD models, this leak can cause the transmission mount to become oil soaked, which will require replacement of the mount along with the leak repair. On 4WD models, if this seal leaks, the fluid will leak into the transfer case, causing it to become overfull.
Intake Manifold Gasket May Leak Coolant or Engine Oil
Engine --
Verified
The intake manifold gasket may develop and external engine oil or coolant leak. In some cases, an internal coolant leak may occur causing coolant to mix with the engine oil. Our technicians tell us that operating the engine with a coolant/oil mix can result in internal engine damage. Replacing the intake manifold gasket should correct these leaks.
