Hello -
No. . ...I agree. . .. . .. . .. . .the way I see it, until my maintenance cost out does a monthly car payment. . .. . ...I work on it :)
Thanks for answering my questions. . .. . .. . ..
I agree. . .. . .. . ...I would at least change the thermostat. . .. . ...but look that one over really good when you remove it. . .. . .. . ..
Prestone. . .. . .. . ...good on you. . .. . .. . .the reason I asked is we have so many different TSBs and other info about Dex-cool clogging up things. . .. . .. . .but both your hoses are hot. . .. . .. . ...
Well. . .. . .. . .. . .I hate to say but I went all through the tech manual I have and I don't have anything other than the pic below on the system. . .. . .. . .which is frustrating. . .. . .. . .
I agree with you in the fact that it is one or the other. . .. . ...but there wasn't a code thrown. . ..the codes I see are like the below. . .. . .. . ...
If it were me. . .. . .. . ..I would change the thermostat. . .. . .. . ...that should take care of the temp fluctuation unless it is the sender per the TSB I located on the temp fluxing. . .. . .. . ..
Next, if it were me I would gently go into the system and operate the controls and see it the actuators are working. . .. . .. . .. . ..you may be able to remove the blower and reach your hand in and see if the door is closing/opening correctly. . ...I think the heater core is right by it first. . .. . ..just a thought. . .. . .. . .. . ..
I think either way it is going to be exploratory surgery. . .. . .. . .. . .. . .
I wish I could provide more on the HVAC but there just isn't any pic. . .. . .. . ...
Then last resort. . .. . .. . ...and please check back if you would like. . .. . .. . ...the climate control but they really didn't provide much info on this system. . .. . .. . .. . ...
I hope this helps some. . .. . .. . .. . .. . .
