I am having an issue with my 98 S70 in the winter where when the A/C is on with the heat up, I get the P0118 code when idling for more than a minute and sometimes while driving. I replaced the coolant temp sensor last year but still the same issue. The thermostat seems fine as the heat works well without the A/C on. This becomes a problem when trying to clear foggy windows/humidity and the A/C needs to be on.
Also to note, in the summer when I am running the A/C for awhile, the cold air disappears and the fix is to turn the A/C off for about 30 secs and it works after turning it back on. Can’t help but but 2 and 2 together and say these are related issues. Has anyone had similar issues? A fix?
