have a 2002 Blazer with 4.3L. Took it to car wash a couple of weeks ago. A couple of days later it rained (naturally). Noticed the airbag light started coming on and off. It'd stay on for 10 seconds-2 minutes. Next day was clear--no light. Rained a few days later, light started up again. Same thing next clear day.

Now it's still coming on intermittently regardless of weather. Saw a post about the sensors being on the driver's side--one inside, one under the body.

What do they look like and how much do replacements cost?

Also, have to replace radiator. What's the opinion of perhaps picking one up at a junkyard? Shop wants ~$300 for radiator + ~$300 labor

Thanks!

anything to do with airbags will be bright yellow, the sensor will be a yellow box, the wire casing to the sensor should be yellow as well as the connection plug.

 

Get a radiator from rock auto and install it yourself, Much cheaper. and not that hard of a job. and for the airbag, war00 coverd it.

 

******WARNING****** disconnect your battery for at least 30mins before attempting to work on any component of the srs(airbag) system also remove the fuse for added measures.

the sensors should be one in behind the front bumper and and im not mistaken one in the rear on one of the crossmembers. if you front the front one the rear will look the same.

 

I used to install high end car audio and knew about the yellow but thanks very much for the reminder . When I "retired," airbags were just becoming standard equipment (yeah, that was a looonnnnngggg time ago!) but a couple of installers at rival shops erroneously used analog multimeters to test the circuit. The resulting load on the circuit was disastrous. One guy suffered a broken nose and the other guy wound up with a dislocated shoulder and a couple of pretty nasty burns.

However, in the post to which I referred, pinktruck mentioned something about two sensors, one under the driver's seat inside the cabin and one under the body in the same area under the driver's seat. She said the one under the truck basically fell out when the bracket rusted away. Any idea what she's talking about?

Thanks again
