The blower lives under the dash on the pass side Look for 12v on the large purple wire with the heater on..also run 12v to the blower to confirm it works. If no 12v check the blower relay in the power dist center under the hood. Also the 30a fuse to it .....look for melting etc...tap on the relay...from this point you need some expertise. Ill help if you want

You will get all the 02 code because of the misfire correct the misfire and the 02 should correct.We will start with the plug wire and make sure the firing order is correct 1996 chevy blazer that will make it a 4.3 engine size check the firing order firing order is 165432 also check the coil (it has a tendency to short you will know if it is) cansmo_181.gifcansmo_182.gifmake sure the distributor rotation is check

Heater wont start or runs intermitently


begine with a test of the motor first,do this with a test light,under the glove box is your blower motor,turn the key on and heater fan and defrost,now ground the test light to a good ground and test the wires to motor,if you have power replace the motor.

1997 S-10 v6, Just replaced water pump. Now I'm not getting any warm air at all when i turn on the heater. It was working great just a few weeks ago. Now it not even geting warm.


You probably have air in the system. Now hat it's run a bit, check the coolant level in the radiator while the engine is cold. You'll probably find it's a bit low. Fill it up and that should fix the problem.

My 02 Stratus heater only works on high. Any idea


Your blower resistor is bad. It controls the mutiple speeds to allow you to go from low/med/high. When it goes bad you get one speed or no speeds....It's about $20-$50 at any local auto parts store. It mounted directly to the speed switch or on the heater plenum unit on the passenger side behind the glove box....
