I got a 94 standard air-condition. The other day the fan stopped working. Opened up the dash didn't find anything out of the ordinary. I put every thing back and now it only works on the 1, 2, and 3 fan setting. For some reason it just turns off when i put it on the highest setting. Even on the 3 setting and max air its still not strong enough to cool/heat the car. Any ideas on what to check or replace, im not too good with electrical wiring but i can try.

IIRC the max setting is a direct relay for full power. The relay can be found in the maxifuse center located on the firewall in the engine bay. Sorry...I'm unsure which one.

alright thanks i can figure that out
