I have a significant wet spot in the carpet on passenger side under the dashboard. After removing the carpeting in that area, I inspected the floor area for possible signs of water intrusion. Does not appear to be any. So I’m assuming there is possibly a leak in the heater core or an area near there. I’ve never dove after a heater core replacement and know very little about them. Is it possible for heater cores to leak intermittently? I’ve only noticed a small drip on the floor after day one removing the carpet and haven’t seen any more since. The weather here has been dry for several days so I can’t really rule out a leak in the cab somewhere. Please share any thoughts and troubleshooting tips to help solve the mystery.
Thanks, Boomer
