heater/ac fan only blows on high.....

my wife owns a 1999 dodge intrepid. since we purchased it new, its been trouble free with nearly 95,000 miles on it right now.

she got in it the other day and the heater/ac fan would only blow on high. no low or medium speeds.....only high.

i immediatly thought it had to be a fuse so i popped all fuses and nada, all fuses are fine. a friend told me that there was a simple fix for this problem but im at a loss. can someone please point me in the right direction. i have never had to do any work on this car so i may need very specific instructions.....photos would also help

thanks everyone.....happy new year !!!

You need this small Resistor unit. It is underneath the dash on the passenger side. I had to replace mine. It has 2 little nuts holding it in so you will need a small 1/8" socket set to get them off. I forget the real name of the thing, but I am sure someone else will help me here. The part itself is only like $15...Very easy to replace yourself

yep, try the resistor pack first. one problem is that it may be blowing because the blower motor is worn and drawing too much current.

see this thread: http://www.dodgeintrepid.net/forums/...or+pack+blower

My 99 2.7 had the same problem. First I replaced the resistor for $15 approx. It worked for about 3 days. Again, only on high after 3 days. Next I replaced both the resistor and blower motor $135 approx. Haven't had a problem for over a year.

Note, it is difficult to get the screws out of the resistor because of where they are located. Good luck!

If it does this again, it is more than likely your blower motor. I replaced my resistor and then a week later it took a shit. The blower was drawing too much current and was frying the resistor. Look for that if this happens again.
