I took my 1996 Aerostar to get a coolant leak fixed. It had leaked down 4 litres+. I noticed the gauge was in the red. ( thank goodness, I saw it ) When I got my vehicle back from the shop the rear heater worked but the front heater didn't. I took it back and they flushed it out to get any air bubbles and now the front heater works and the rear heater doesn't work. Could it be the controls that are faulty. If so, is that very expensive. I'd rather have front heat then rear heat for defrost etc.
Or could it be something else? It's odd that I get one or the other but not both.


Thanks, I'd appreciate any advice.

 

I'm not the least bit familiar with an Aerostar but it does sound like a control issue. Given that one heater core will work but not together says you have circulating coolant which is good news.

Sorry I can't be more specific in helping solve your no heat situation.

Best of luck!

 

Thanks for replying. I have the "all Important" front heat so maybe I'll leave it at that for now.
