Help! TPM confused
My '03 C5 is new to me. I love it but still learning.
So the dash display showed my LF tire was low. I took it to a tire center and they did not find a leak but they cleaned off the rim bead and installed new O rings on the TPM. A few days later it's low again so I took it back and I think all they did was tighten the valve stem some more. Today I went out and the LF read 26 psi on the dash display while the right was 32. I didn't have time to fool with it so I just put 35 pounds in the LF and figured it will leak out. Then as I drove I saw the dash display showed LF 26psi, RF 36psi!
Long story short, it looks like the readings are backward. The TPM on the right shows up as LF on the dash and vice versa.
Is there a way to re-program these? Or do I have to physically switch them? I've only had the car 3 months but it came with its 2nd set of tires so I wonder whether the installers switched the rims by mistake.

Thank you! btw I did look in the owner's manual but did not find this. Anyway--the video is probably better.
PS: Just checked the manual again and this info isn't in there. On page 3-53 under "Tire Training" it says to "See your dealer." So this video is REALLY helpful.

A follow-up: Directions in the video worked perfectly and now my TPMs are no longer confused. Thanks 8VETTE7 and CorvetteOnline!
Here's a tip: You need a powerful donut shaped magnet to put over each valve stem. I happened to have a "Medtronic ICD Detection Donut Magnet" a friend gave me several years ago and it's just the thing. So if you need to re-train your tire sensors look on Amazon or ebay. They seem to only come in a 2-pack and they are $20/pair on Amazon, $25 on epay.
