Hi,
I have a 2003 4Runner V8. A couple weeks back I took it in for service at the local dealer to have the AC looked at (wasn't blowing cold). After there and about $210 in labor, they told me the electrical system was messed up. While they were testing they claimed the dome light stopped working and then the blower gave up. Apparently they found remnants of a mouse house in the engine bay and were pointing at mice having eaten through the electrical system somewhere and causing a short.
Anyway, not wanting to buy a new 4Runner I went digging in my own. Dome light wasn't working because the relay was missing from the fuse box! Seems like they forgot to put one back in. So that got me thinking that maybe they messed up something on the blower or heating/cooling system. Took the dash apart - nothing out of place. Tried replacing the heater relay, blower, and resistor and still nothing. All the fuses seem check out as well when tested. Is there anything else I could be missing or could test before I throw in the towel? Love my 4Runner and would hate to have to get rid of it. I have the whole service write up as well if that'd help. Thanks!
