Question about 1988 Chevrolet Corvette
I have a 1988 corvette... the climate control has gone bonkers.. i have cleaned the contacts on the unit.. changed nothing.. i can hear the compressor engage.. but the fan does not come on.. tried it on the "auto".. econ.. and bi level settings.. with "auto" and manual fan speeds..
could it be the climate control head.. fan motor.. or the entire control unit ??? any way to narrow it down..?
any help would be appreciated..

You should make sure you have proper charge for sure.has your battery gone dead lately? I know on some of them digital climate controls will act exactly like this and have to be reset or go through a setup sequence.

SOURCE: ac not working
if you by passed the relay and clutch engaged then this shows that pump works ??but was it getting cold on and around the restrictor valve where the pipes enter the cab is normally a valve block but american monsters use a valve in the pipe for cooling and if its not getting cold their or blowing cold inside cab then system needs re-gassing with R 134 gas if its an older system with R 12 gas then it will need to have adaptors fitted to valve connections and refilled with R134 gas.The main cause of A/C system loosing gas is porosity in the rubber flexible pipes also the back seal on the pump.Or just regass and put a leak stopper in the system

Check the relais module located inside under the rh side of the heather box you can see the connector most of them need to be replaced as they burn out you may need to replace the blower motor as well,high amp draw caused by faulty bearings will overload the blower motor controller

There is a way to retrive the diagnostic codes in the A/C system by holding 2 buttons at the same time on the panel. I did this many years ago to solve a problem on my '92 Roadster. I got the info from corvetteforum.com Post your problem at corvetteforum.com. There are many experts there that will help.

Your A/C system has lost its refrigerant, and will automatically go into "ECON" at that time. System will have to be leak tested , repaired, and recharged. Hope this helps.
