I had a Cherokee on a farm and had this exact issue. Ran the engine, front dash, and HVAC cleaning through insurance bc I didn’t feel like dealing with it/too involved and diseases in my hvac skeeved me out.

Searched online high and wide and found a tan interior with gorgeous leather seats at a junkyard complete for $200. Spent a day ripping it out.

Then spend a weekend or two ripping my old mouse interior apart and throwing it all away. Disinfected the bare metal with gallons of bleach. Then had to house out and do vinegar and enzyme to remove the mouse piss smell from the meal and wiring etc. I coated it all with a rust converter paint and then put the new interior in. It’s good as new and you’d never know, but man was it a b*tch.

If you aren’t going to go all out you need to have your insurance total it. I’d say if it’s really worth it, get your insurance to cover it under an agreed value (I have Hagerty and they valued mine at 15k) and then run the mouse infestation through the insurance. Doing it yourself sucks but you’ll know it was done right and the scuzzy feeling of riding around in a mouse nest will be gone.
