I pulled the codes today and code B0338 HC displayed. Code will not reset. The code is for "inside air temp sensor open". Searched and found this link: https://www.corvetteforum.com/forums...uto-targa.html
One of the posts states:
"the cabin temperature sensor is located inside the little plastic pop out tab that is on your driver side dash - right next to the ignition switch. It is very easy to access.
Sensor open usually means 1 of 2 things.....1) the sensor has failed....or 2) the wiring to the sensor itself has been damaged or has come loose."

Can someone show me a picture of the tab, where it is exactly and how to open it so I can check it.
Thanks.

Take a small flat bladed screw driver and slip it in on one side and pop it out
it's right beside the ignition switch...

laurent_zo6

Thanks. How do you pull it out. Do you twist it out or?

73Corvette

No it has to small hooks on both sides just pry it out from the side...pops right out.

Thanks. I will take a look at it and report back when I find the answer.

Here is the answer to my original post. I took my time to fix it because the AC seemed to be working ok.
Had to take my car to Rick at RKT Performance for a few minor problems. I asked him to check the code. Turned out the sensor was defective. That part is no longer made by GM. That's really incredible. Rick called around and found out that AC Delco makes a comparable part. There was one left in a parts dept not far from the shop so he had the part delivered the same day. The part works perfectly and no more codes.

So you're not going to share the GM part number?

laurent_zo6

Rick took care of the problem. I can ask him if you would like. Why do you want the number of the discontinued part? Don't you want the AC Delco part number?

dadaroo

Yes, the AC Delco number is what you should be sharing. I used the term GM since they are owned by GM. Whenever they use an AC Delco part they show the GM number and the AC Delco number in their parts book.

My GM parts book shows the AC Delco part number as 15-72496.

If that is the number your guy Rick used then it is not a comparable part, it is the original OEM part.

laurent_zo6

You have the correct part number. It is AC Delco # 15-72496.

dadaroo

I know that is the correct OEM part number. What did your mechanic put in your car?

laurent_zo6

That's the part he put in the car.

Replying to an old post in hopes of some advice. I can’t find this part anywhere. Has anyone found one recently and can let me know how to find one?

laurent_zo6

That part appears to be discontinued. Your bet bet is to call Corvette salvage yards.
