02 Buick Rendezvous doesnt heat all the time. Temp gauge goes all the way to red when idling,then goes down when driving,with heat.Had a problem at one time with Dexron antifreeze,it was all "foamy" looking at radiator,changed to the "green"antifreeze.Problem is very intermittent,and seeing as how its starting to get very cold,the wife aint gonna be happy if she has no heat. Any suggestions are greatly appreciated,thanx.
