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
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
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.
