1990c4
hello , last year i bought a 1990c4 from original owner 39,000 miles.
runs fine and everything works untill today.
had AC on and then blower stopped , small digital readout for temp for heater/AC went blank and the antenna won't retract.
put 12v to blower motor and it works.
anyone know if there is a common fuse or relay for these issues ?

yes there is a single fuse for all that, plus the under hood lights.
Open passenger door, fuse panel is on side of dash, the fuse is in the upper left corner 15 amp
If the fuse blew, it blew for a reason. But, that fuse is pulled to intentionally disable the under hood lights so maybe it was some user error like it was replaced with a less amp fuse or wasn't properly pushed in so you could get lucky and it's just something easy like that.

thanks for reply ,i'll check fuse this AM , AC did work fine last july & august
i would imagine all fuses are original 30 years old- everything else is except for alternator & serp belt which original owner replaced and i just replaced shocks with KYB;'s and brakes .

If you do have the C68 Electronic Air Conditioning Controller you might want to figure out why the fuse was blown if possible. The C68 does not have the mechanical slides for temp adjustment just to identify it better.
While rebuilding my Digital Dashboard with the great help of BATEE,com I learned that the C68 has several weak links that need to be updated if you want to continue using it (reliably). There is a ribbon cable that connects two cards and the connectors were badly warped and the wires in more than half of the connector were not making contact. BATEE can get you the parts and do the repairs for you if you want them to. The other option is to get the parts and do the repairs yourself.
BATEE is an incredibly useful resource for we Corvette Owners with Digital Dashboards and C68 controllers. He has several pages of very useful information at his web site. I am so grateful to BATEE for keeping our dashboards working. This is another one of the "Business' to remember".

HA!!! it was a dime in the lighter socket the C4 is my wife's toy i never drive it as i have a 1975 datsun 280Z.
we don't smoke so the lighter socket is used for her phone charger.
no more change is going in the ashtray/cupholder.
