1996 Dodge Grand Caravan Q&A
1996 Dodge Grand Caravan Question: heater blower runs on high only
When the blower runs only on high it's usually the blower motor resistor. The 1996 and 1997 Caravans may have an issue with corrosion on the connector terminals on the resistor. Look for any corrosion on the terminals. Dodge has a revised resistor and a replacement wiring connector. I searched google and this page has great images of the condition. I hope this helps! You'll need to copy/paste that entire link I'm afraid it didn't copy correctly. http://www.automotiveforums.com/vbulletin/t340871.html - Andy Y
the most frequent problem i have ran in to with those conditions is the blower motor resistor block. the high speed power does not go into resistor block, it has its own power. replace blower motor resistor block to fix that concern. - Visitor
The fan will only run when you put it on high. A friend of mine tested the switch and it was good.
