First, the easy way is to just bypass the relays all together. Install a switch on the inside of the car like you would fog lights. This will solve the problem of replacing thing after thing and wasting money. Just a $7.00 fix. After doing that unplug all the sensors and then the battery for at least 60 second to reset the computer. Than restart the car and the check engine light should go out, may take a day or so. Same thing with your gas cap, re-securing it will take a day or so for the light to go out. Good luck. I love my '97 neon.

Did you replace the sensor by the thermostat in the engine block or the one under the drivers headlight, There are two, the one next to the thermostat controls the temp gauge in the vehicle. the one under the headlight assembly controls the actual fans and is a electronic module. You have to remove the head light assembly to get to it.

SOURCE: blower motor will not work
Do further tests at the relay to ascertain whether the fault lies before or after the relay.
Check power availability at the supply side of the relay contacts - should have 12v from a supply fuse on one side of the normally open contact (note -this supply may only be available when Ign or Acc sw is on).
If power supply is ok at the relay contact, check control input to relay operate coil.
If a ground (or 12v) operates the relay, operate the relay with a local ground (or 12v) and check blower motor runs.
If all above OK, check control signal from fan switch is arriving at the relay control coil.- if not trace wiring back to the switch.
