Radio issues possibly electrical

As mentioned known issue and the only fix I have had is to put in an aftermarket stereo. You may find information about checking the fuses but I have never seen this fix work so I would not waste my time. If you attempt to get one from a salvage yard make sure it is the exact same OEM part number which will be found on the label of the radio. As far as the Head Gasket leaking there is only 1 permanent fix and that is to replace it however if you cannot do it at this time here are a couple of products. Bars Leak and Blue Devil I have the links below. I do not endorse either of these companies nor do I take any responsibility for your using them. Both have additional products to help seal leaks and I know Barr worked great on my Water pump. https://barsleaks.com/gaskets/fixing-blown-leaking-head-gasket-one-affordable-easy-step/ https://gobdp.com/symptoms/

It sounds like your radio ACM is going based on the issue you described. Luckily, this is a very easy fix. You can buy an after marked ACM on Ebay for anywhere from $50 - $100, I purchased mine from the seller "Discount OEM Radios". There are plenty of YouTube videos online showing how to replace them. It's a really easy fix. You will need a trim removal tool or butter knife and a 7mm socket wrench to open up your front console. From there, it's a plug & play part. Just make sure before buying that the part on your current ACM is interchangeable with the new ACM you're buying. Discount OEM radios will assist you with this too. Good luck.
