Heater not working
Question:
Try replacing the a/c control panel, they are frequently defective on S10s. Michael
Response:
You need to explain this better. What isn’t working? the fan, hot air, wrong duct output,all the above. The fan problem was covered in the previous post, there could be a vacuum leak which would cause the heater/AC, vent and or modulator doors not to function till the vacuum built up enough. If you can furnish more detail I’m sure we can point you to it.
