Default Half Hot, Half Cold

Have a 1998 Convertible. Living in a climate where driving all year long is not possible but would like to stretch it out as long as I can. Here's the thing. On those chilly days when you want to work the heat just a little to take the chill out of the car, I get warm air on the passenger side and only cold (frigid) air on the driver's side. Any simple or inexpensive ideas for solving this dilemma?

The 98 I used to have did that when it needed Freon.

If you're wanting heat on the drivers side and can't get it, most likely a blend door problem. Just had this on my car. Have to remove the dash pad to replace the blend door actuators. I used a dorman product from O'Reilys $150.00. You can buy the same one on Ebay for 40 some dollars if you have time to wait for shipping. Not all that hard to do but is time consuming.

I would start by going into the DIC and clear all HVAC codes, listen for the doors to cycle. Once you try that see if you now have heat/cold out of both sides.

Does any one have an illustrated on how to replace both blend door actuators? that would be a huge help. I don't mind replacing both while i have the dash apart (just to make sure)! is there any other things in the dash i should look while doing this repair? Or any repairs to make while the dash is apart? I have a C5 that i am need to do the work on.

When I first got my car, this was the first repair that came up. Unfortunately, back in those days,I hadn't joined this great Forum and was too scared to put a tool to the car...dealer charged $650 for the repair if my memory is correct. Shortly after being on the forum, I wasn't scared to tackle a lot of things.

Had same problem on my '97 Caddy. I think dual temp blend works same on our
vettes. Got under dash and manually operated blend actuators through a few cycles. No problem since. Otherwise you will probably need to replace one of the actuators.

Disconnect the battery for a good 24 hours. Worked for me.
