1992 GMC 1500 suburban SUV heater will not work does not blow air no heat no noise
What is your question?
Purchased my 1992 GMC suburban SUV c 1500 one and a half months ago. ended up stalling while I was driving replaced the battery then replaced alternator. Now he's a will not work. It never worked right since I bought it the window light gauge for the heater never lit up. The heater was barely working and would only warm the car. Now it doesn't work at all since replaced battery and alternator.. I haven't noticed any loud noises or odd things going on with that except for the window light never worked and it worked barely before replacement of other items
What makes this problem better or worse?
It's almost as if it had no heater at all no noise no air no nothing. Rear defogger light comes on yet no fan or heat or noise
How long has your 1992 GMC C1500 Suburban had this problem?
Bought car 1 and 1/2 months ago wasn't working properly then no light showing gauges of fan etc. Heater barely worked barely blew out any more mare. Replaced battery and alternator 2 weeks ago
RepairPal Certified shops can diagnose and repair your 1992 GMC C1500 Suburban. They provide transparent pricing with a minimum 12-month or 12,000-mile warranty on repairs and services.
Due to the complexity's of today's vehicles the majority of owners or DIYer's do not possess the proper diagnostic equipment nor the knowledge and training that's required to effectively and successfully perform their own automobile troubleshooting / repair.
Therefore it is highly recommended to seek professional *hands-on* assistance with this issue as that tends to be the most cost effective solution..
We could post a 'list' of the possibilities - however that isn't going to help due to the fact the same diagnostic equipment and troubleshooting knowledge is still going to be required.
Good luck!

A heater that will not blow air has a concern related to the operation of the blower motor. This could be related to heating control concerns, fan switch concerns, wiring and connector concerns, blower motor concern. Testing is needed hands on to find out what is happening.
