Well its my turn for the Aux fan to go. Its 115* outside and the suburban had both front and rear a/c going. Well, I noticed the temp climbed up to 230*+ and it started to run bad. So, we cut the a/c (kids weren't happy) to get the temp to go down, which it went down to 210* and it ran good. After we stopped I jumped out and told wife to turn a/c back on to get it to climb again, which it did, and no fan came on. So, I am pretty sure with a/c on and 230*+ it should have come on. Is this replace easy, swamp out the old and in goes the new?? Any upgrades should I do?
TIA
