Air conditioning on all the time?

[RonJ]

I noticed that on my 98 with Dual Climate Control, that the AC indicator light is on all the time, even if I turn the temperature up as far as it will go. It seems to work fine, cool when asked, hot when asked. But the light never goes out.

I checked the codes, I get 99-HVAC/ B0338HC. This translates to INSIDE AIR TEMP SENSOR OPEN.

Is it common for this sensor to go open or is there a good chance that a poor connection exists? I'd hate to buy a new sensor and then find out something else is the problem. Do I have to pull the dash apart to get at it or is it right there beside the ignition key?

I'd appreciate any input ....

Thanks, Ron ....

Your inside temp. sensor is next to the ignition key and prys out with a flat blade screwdriver.

Here's a pictorial which includes removing the temp. sensor.
