Sorry if this has been asked before, I looked and couldn't find anything. Provide link please if this is already posted.
I am having a heat issue on my 04 Caravan 3.3L. It's getting cold here and I have on sporadic heat coming from the vents. The heat gauge goes to about half then I get a burst of heat then the needle drops and then I get nothing. From what I can gather this is a thermostat issue. Is replacing a thermostat a DIY thing? I called around and they want $150 to replace this thing. From what I can tell this looks to maybe be a 10 minute job. Am I totally wrong? Should I just pay the $150. If not, anyone have a guide? Also, I hear there's TWO thermostats in my van, any ideas which needs to be replaced?
Thanks for any help you can provide.
