CatAk98

Hello, would the WD-40 be something to try on a 98 Riviera? I have an odd problem where the automatic windows appear to only work when it’s cool out...the car is not driven often and has a few problems; however, has sentimentaL value. Would like to start with the windows as the A/C not working is one of the problems! They work great in the morning, but as hot summer day progresses, they do not. Has anyone heard of this? If I park it in the shade and wait a bit, they will work again. Sounds like I’m reaching, but this seems to be the problem and it only happens in hot weather. Thanks!
