For the last week or so, my climate control will not work until the car has been driving for atleast 15 minutes. No heat, no air, no fan. Then, a relay somewhere in the dash starts clicking on and off, and then the climate control comes on. Sometimes I can get it to work sooner by turning the car off, then back on thereby making the relay work again. I remove my climate control panel but to not see any relays, and having just resoldered my climate control cluster last month, I know there are not any relays in there. Any ideas? I think it's just dirty contacts inside the relay, but I don't know where it is.
