Post by spyboy »

First there was a strange smell coming out of ac then no high speed fan on max AC other speeds work well and no smell. The smell was sort of sulfur like.

Sounds like it's time for a blower motor resistor. Pull the rad. overflow bottle and you will see a six wire plug. Behind the plug is the resistor. Check the plug for melted connectors. I changed resistor once. Second time I changed blower motor, resistor and plug. Worst part was cutting the plastic cover to get the blower motor out.
Good luck
